Greetings all,

I'm in the market to buy a 1980s-era Mercedes 300D. I've found a good
deal on one that has been modified to run on vegetable oil, but which
has 248k miles.

Assuming the vehicle has been properly maintained, what is the expected
lifespan of the engine? 248k miles seems like a lot to me, but then
again, the only vehicle I had that came close to that was a gas-powered
1982 Volvo which was still running strong when I sold it a few years ago.

Can I expect it, with proper care, to run to 500k without many problems
or loss of power?

Are rebuilt engines available? If so, what can one expect to pay for
them?

I realize that engines are quite expensive, but these cars have
character. Either way, I'd like to ensure that the vehicle would have
options available if there were to be engine problems.

Thanks for any information.

Cheers!

For what it's worth, my '85 300SD (same driveline as the D) has better than
225,000 miles on it now and has no problems whatsoever with the engine; in
three years I've had no problems, and there's no indication that the
previous owners ever did, either. The 5-cylinder 3.0L Mercedes turbodiesel
is renowned for its
longevity, as long as basic maintenance (oil changes, valve adjustment) is
kept up. With recently-replaced glow plugs, mine still fires up immediately
in winter. If I had to guess what problems I might expect in the next
hundred thousand miles, engine trouble would probably be the absolute last
on my (very short) list.

I don't know what effect vegetable oil has on an engine's reliability,
though it's probably negligible. I have heard of Mercedes diesels that have
been converted and run fine.

Excellent. I'm nervous about buying a high-mileage used car, even a
quality Mercedes[1].

I've been told that Mercedes maintenance and service can be rather
pricey, particularly with older vehicles. Is this the case?

Agreed. I doubt it has any sort of negligible effect. It'd sure be nice
to drive on practically free fuel, while being able to switch to regular
petrodiesel when on long roadtrips away from the dispenser at home.

With 248k miles on the Mercedes odometer already, do you think it'd be
worthwhile to sell my 2003 Honda to purchase it? I've been doing a lot
of reading at Edmunds.com, and I'm not entirely convinced it's a good
idea.

Now, if it only had <150k? Different story altogether, and something I'd
jump at. But nearly 250k? It gives me pause.

[1] In order to buy this car, I'd need to sell my 2003, 20,500 mile
Honda Insight hybrid. I like the car, but I need a backseat, a trunk,
and a more durable body. The plastic/aluminum body takes a beating, even
from normal road conditions (in two years, I've put more than $6k into
bodywork, $3k of which was when my sister backed a Buick into it 2 weeks
after I bought it. The rest were just normal wear-and-tear, like a rock
vs. hood/windshield, which cost $1,400.). The Mercedes sounds good, but
is it worth selling a two-year-old, low-mileage car for? Are they /that/
reliable?

248K IS a lot (mine has over 300K). You have to include other factors, such as the condition of the transaxle, transmission, all the
other mechanical bits and pieces.  There are many excellent cars out there with much less mileage, don't hurry, find a good one that
has been WELL maintained. Make sure you get one that has no oil loss. MAKE SURE that the transmission fluid level is proper.

> I've been told that Mercedes maintenance and service can be rather

Any badly maintained car will be pricey. If old benzes were costly to maintain most of the people on this board (including myself)
wouldn't be driving them. We have 5 benz diesels in our family and we're definitely happy with them.

BAD idea. 248K is too much. Look for another one, check out ebay for nearby cars.

It's NOT a good idea. 248K is too much to buy.

I wouldn't get it.

Aren't you going to lose a lot of money selling it?

They are that reliable. My friend has a 1958 that he uses for daily driving. :-)

Pete Stephenson - 19 Aug 2005 15:37 GMT
> Aren't you going to lose a lot of money selling it?

Surprisingly, no.

This is the Bay Area, and there's a large market for hybrid vehicles.
Many people use them as some sort of political statement.

I bought it at $20k-and-change in '03. I got an offer for $15k the other
day. With about $6k of bodywork put into it[1], it would seem that I
would come out slightly ahead. Even without the bodywork, I'm rather
surprised that a low-volume, never-very-popular car hasn't depreciated
far more than that.

2000-2002 Insights are selling on eBayMotors for about $10k, and they
have ~100k miles. This only has 20.5k, which is quite good.

Getting back to the Mercedes, I'm curious...on one hand, you say that
"they /are/ that reliable", yet also say that "248k is too much to buy".
How does that work?

Unfortunately, late-80s/early-90s 300D series vehicles with less than
$100k miles do not seem to exist, at least not on Craigslist, which has
numerous ones locally. Many of them have in excess of 200k miles. That's
what's in my budget, and the years when Mercedes seems to have made Good
Diesel Engines. Newer ones are much too expensive for me, and there are
several years where the number of diesels produced was rather low.

[1] Again, the body is rather...delicate.

248K is too much too buy because of potential work to be done. Of course, if you're getting it dirt cheap then definitely get it.
Once a benz is "stabilized", everything done, it will keep on going. Other cars just fall apart. Not all of course.

If they're cheap then it's worth it but find out what has to be done, look for affordable mechanics, get everything done and the car
will be fine.

> and the years when Mercedes seems to have made Good Diesel Engines.

From what I hears whenever I'm in Europe, they're still excellent. Though there have been issues of course. My uncle has a Sprinter
which he uses to deliver produce, couldn't be happier with it.

If you can get it cheap and fixed inexpensively then it's worth it.

Here's some good advice; go on some local forums and search out other benz fanatics and ask them for any good, reasonable mechanics,
there will definitely be some around.

And another piece of advice; do NOT take the car (if you buy it) to a dealer unless as a last resort. It's ridiculous how many
people bring old benzes to the benz dealer and then complain what a ripoff benzes are.

You don't state if this is a turbodiesel (120 HP) or not (77 HP). Buy
only a turbodiesel, same fuel use.

The five cylinder diesel that you want to buy is a very tough and
durable all cast iron engine. That said, given normal maintenance it
should go 250K - 275K miles +/- 10%. Given very good maintenance 300K etc.

However, by now this car has been owned by X number of people, some of
them were good to it others perhaps not, so it's incumbent on YOU, for
its your money that's at risk, to have an independent M-B shop verify
the engine's actual condition with a compression test. That's the ONLY
diagnostic test that will tell you its internal condition (short of
taking it apart). This will cost about $100 (request an estimate) but
then you'll know if the motor has many miles remaining, or not. And if
not then you'll be happy to have limited your expenditure on this car to
$100.

Rebuilt engines are available for $3,000 - $3,500 but realistically few
twenty year old cars merit that cost so a used engine ($800 - $900 +
installation) is the usual alternative.

Don't get too excited about saving money on fuel, the 24 mpg economy
doesn't offset repair costs. This will only work as an economy car if
YOU do all the maintenance and most of the repairs. If ownership and
running cost govern and fixing cars isn't for you then buy a high volume
car that any local garage knows how to fix.

It's the turbodiesel model.

Hmm. Considering it already has 248k miles on the clock, that doesn't
sound very good.

I was under the impression that Mercedes diesel engines had
significantly longer lifespans than what you quoted above, assuming
proper service.

Agreed. I happen to have a most excellent mechanic shop that specializes
in Volvos, BMWs, and Mercedes. They offer pre-purchase inspections for
$125. When I owned a Volvo, I had it serviced there for 13 years. They
are trustworthy.

Would a thorough inspection by a well-qualified shop be able to
accurately (within reason) estimate the lifespan of the car? You know,
like "Oh, your engine has about 150k left in it, your interior looks
great, and all the wires and vacuum hoses should last for the
foreseeable future...".

Hmm. Something to keep in mind, thanks.

I have a Honda Insight (two-door hatchback hybrid) that I rather like,
except I'm looking for a vehicle with a back seat, sizeable trunk, and
is more rugged/durable. Diesel-powered is preferred, due to the ability
to run on biodiesel and vegetable oil.

Assuming the car is in good shape, and I will hopefully be inspecting it
shortly, my main worry would be the drivetrain (engine, transmission,
etc.). If the engine is nearing the end of its service life, that could
be a problem. Similarly, if parts of the car start breaking or
malfunctioning, that could also be an issue.

I don't mind turning wrenches every now and again to fix something...but
the Mercedes /was/ designed as a luxury car. With regular service (i.e.
oil changes, fuel filter changes, etc.), I would hope that it would last
pretty much indefinitely in terms of most interior parts not associated
with the engine. Sure, a speedometer cable might wear out, and I can
easily replace that. But if I need a new engine, a new transmission, new
headliner, new instrument panel, etc., that would definitely not be
worth it.

Let us assume for a moment that the vehicle is in good working order. No
repairs are necessary, and all that's needed is the standard regularly
service at pre-scheduled intervals. What's a ballpark figure for these
costs? I take my Honda in for an oil change every 3,000 miles at the
local dealer (they have good pricing on service), and it costs me about
$40. Regularly scheduled maintenance (i.e. 5k, 15k, 30k, etc.) costs a
few hundred bucks or so (no more than $300-$400, so far). This is for a
car with 20,300 miles on it. Do you have any idea what I would expect
for the Mercedes, assuming that there's no major repairs necessary?

Having a vegetable oil/biodiesel-fueled vehicle would cut down
significantly on my fuel costs, which, even with a hybrid, are the
biggest costs I incur with my vehicle. Assuming regularly scheduled
service is able to keep it in good working order, I should actually be
able to save money over my current car. However, if things start falling
off, or the engine wears out, etc...that could be a major issue for me,
and I'd stick with the Insight, small trunk and all.

Thanks for your help -- I'm looking to make an educated, informed
decision and am consulting sources ranging from Edmunds.com, to this
group, to several diesel-savvy friends I have. Your knowledge and
experience is extremely helpful.

Aside from the engine,do an inspection throughout the entire vehicle
for rust.You did not specify if this is a W123 or a W124 but if a
W123,pay close attention to the floorboard(lift carpet up)especially at
the accelerator pedal and the seat base.In the trunk,look in the side
pockets and underneath that section also,plus the rear wheel arches and
mounting area of rear bumper.When you open the doors,look at the
underside of door and where the seatbelt fastens to the pillar.Hope I
didn't scare you on W123's forever but thought I would add.
T.G. Lambach - 19 Aug 2005 20:03 GMT
I've owned a 1980 300SD since new; it now has gone 109K miles. I keep it
garaged and in top condition. It's a great car for local use; we use a
newer, smoother, quieter and more powerful car for trips.

The diesel's repair and maintenance cost approximately equals its fuel
cost: 8 or 9 cents (now probably 11 cents) per mile, insurance excluded.
I do the valve adjustments and small repairs, a shop does the oil
changes and any major work. That's its long term economics.

In reading your posts, it would be a big mistake to trade off a two year
old car for a twenty year old car, IMHO. I say that despite my owing a
25 year old car, but mine was bought new and I know it well so there are
no buyer's surprises hidden away somewhere.

Indeed. Hopefully by running on free waste vegetable oil, I should be
able to cut expenses even more.

I don't mind doing work like that on the car (leaving the oil and major
work to the shop), in fact, I'd rather like it. :)

I agree. That doesn't make much sense.

I'm going down today to examine and possibly test-drive a 1992 300D,
which has 198k miles. According to the owner, it's in good-plus
condition. Obviously, a thorough examination will determine if that's
the case.

While perhaps selling a 2-year-old car for a 20-year-old car isn't the
wisest of choice, selling it for a 13-year-old-car would be a bit
better. About 50k less mileage, less wear-and-tear on the car, etc.
Probably a better AC too.

There's another car, an '87 300D with only 119k miles which might also
be something to consider. Same price as the '92, though I may be able to
negotiate a bit on both vehicles -- they're asking double the Blue Book
private-party price.

The guy selling the '83 veggie-oil car also does conversions for a
living. I inquired as to the cost of converting the engine to veggie-oil
(it can, of course, burn regular diesel as well) and what the cost of a
home filtering/fueling station would be. It would be a far better choice
to get a better vehicle with fewer miles on it and do the conversion
than get an older, more worn vehicle with the conversion kit already
installed.

And I certainly wouldn't feel uncomfortable selling my 20,500 mile
Insight for a 119k Mercedes. 250k, that's a bit much. 198k...I'm not
sure. Depends on the rest of the vehicle and a thorough inspection.

Amazingly enough, I just got an offer for $16k for the Insight, which is
excellent. We'll see. :)

I believe the '87 300D has a six cylinder 148 HP turbo diesel. Nice
engine, smoother than the older five cylinder engine BUT cannot be
overheated. This engine has hydraulic valve compensation so there's no
valve adjustment requirement.

This '87 may be something to look at seriously due to its relatively low
mileage. If you buy it be sure to maintain its cooling system well.

Not many '87 diesels were sold.

Good thing to know. How does it compare in terms of horsepower and
torque?

What about early 90's (1990 to, say, 1992) diesels? How do they compare?
Still have the tank-like feeling?

*nods* Proper service will, of course, be done as recommended by the
manual and mechanic.

I'm also thinking of doing the GreaseCar.com veggie-oil kit, probably
doing it myself.

> Not many '87 diesels were sold.

Indeed. That's what the seller claims, using it to justify their
double-blue-book-value asking price.

Go to any diesel pump and drip a few drops onto your hand - and then try

Hopefully I wouldn't be doing much with actual diesel fuel in the
garage. More like work with vegetable oil. I'm hoping to make an
arrangement with a local diner (that I'm a moderately frequent customer
at) to have them set aside some oil every week for me into a plastic oil
drum.

Hopefully the filtering/fueling system at home would be a sealed system,
so I just need to bring the drum back home (and leave an empty one there
for the diner), let it settle, filter it, and pump it into the "ready to
fuel" drum. I'd strive to have it work with practically no open
containers, so the risk of spilling would hopefully be low.

The thought I'd raise isn't with longevity.
Several friends over the years have taken their MB diesels
well into the 400k range.  Even if this one would do that well,
subtraction will tell you more.  You've got probably 125K left.
That's not a lot.
Here in Columbus someone this week is selling a '91 350SD for $13K with

a little over 100K miles.  That would be a nice diesel to start with.

trader4@optonline.net - 19 Aug 2005 14:56 GMT
The car has 248K miles on it, which is at least in the range of the
typical lifespan.  Unless the rest of the car is in pristine condition
and you are prepared to spend $4000 to have a rebuilt engine installed,
I would walk.  You also have to be prepared to deal with lots of the
other components that you can expect to go at this mileage and age.
Things like vacuum hose connectors and actuators, window seals, etc.
Some of these are dependent on age, as well as miles, as plastic/rubber
deteriorates over time.  Many of these smaller things don't cost that
much to fix, if you do the work yourself.  However, if you're selling a
2 year old car to buy this one, this would likely be more aggravation
than you are prepared to deal with.

A friend of mine still drives his 1993 300SD Turbodiesel
(as it was called then, W140) from new, now has circa
150.000 km (ca. 95k mi) and never has had any problems

It would be helpful to state clearly what you are
talking about:

W123 300D
W123 300D Turbodiesel
W124 300D
W124 300D Turbodiesel

because they have different engines and
different bodies.

It would appear to be the W123 300D Turbodiesel.

My apologies, I did not know there were different models of the 300D for
a particular year, other than with/without the turbo.

No apologies needed - but as these cars are different
it simply is vital to know which model to talk about.

Ok, now for the W123:

The 300D Turbodiesel engine is sufficient for todays
use, but it is no fast car.

Keep in mind these cars are old - so check carefully for
rust.

Typical are:
Front fenders, below the bumper, there is a welding seam
running in the space between the headlights and the
turn signals _below the bumper_ - the massive US bumpers
prevent an unhindered sight.

Sunroof frame - open the sunroof and look into the dark
frame from atop

All four car-jack holes below the doors

Wheel arches - often beginning rust is covered by
chromed wheel arch trim

Doors, open them, look carefully under them, often rust
is where you can not see it easily towards the front
bumpers (to door hinges resp. A- pillars) resp. towards
the front doors (to door hinges resp. A- pillars)

Station wagons - rear door, especially lower part

Indeed.

Update: Today I personally inspected[1] a 1992 300D (not sure of any
sub-models, but it had a turbo). 198k miles, but according to the wear
on the mats and pedals, it looks to be almost entirely highway miles.

Current owner says he bought it from a woman who used it almost entirely
for highway driving back in 2001, and intended to ship it down to
Uruguay, where he lives for a few months out of the year (gas is
expensive and diesel is cheap there). Turns out that shipping is quite
expensive, and one would need to pay an import tax based on the
Uruguayan sale price, which is nearly double that here in the US.

According to him, he's only put about 3k miles on it since he bought it,
as he drives a Volkswagen around a lot more. Car's been garaged with a
cover for all that time. He says the previous owner also kept it garaged.

Body is in incredible condition, with only a few very minor dents (but
no associated paint scratching or cracking -- no signs of impact either)
and scuffs on the plastic of the bumper. Far less than I'd expect for a
13 year old car.

Interior looks really great too. Only problems I noted here were that
the ABS light was on (seller said he'd investigate and have it repaired
if necessary before the sale), and a small crack in the fake-wood trim
right by the ignition, as if someone missed the keyhole with the key. As
long as the ABS works, the little plastic bit doesn't concern me much.
Hardly a deal-breaker -- are these pieces available on eBay? Could one
just secure them with adhesive after removing the old one? All
electrical, rubber, and other parts I could readily access look to be
great. Lights are bright, with no flickering. Everything looks solid.
The only odd things was that the oil-pressure gauge kept going between 1
and 3 depending on if I was pushing on the gas or not (is that normal?)
and that the temperature gauge seemed a bit low, (~60C), even after 15
minutes on a test drive.

Engine looks to be incredibly good. No signs of being steam-cleaned, or
otherwise made to appear better than it is. Normal grit and grime from
an engine compartment is present, but things look clean. Hoses are
supple, engine sounds good (though has a sort of metallic ticking noise
when running, which I believe is normal for diesels). Transmission was
smooth, and handled cruising (with and without cruise control, which
worked) and strong, higher-rev acceleration on onramps. I didn't want to
goose this guy's engine too hard, as it /is/ his car, but it seems to
have sufficient performance for my need. He also had European-style
headlights (which I like better) installed fairly recently, for reasons
unknown. My friend says that it may appear that the hood had been
repainted at some time, possibly by the previous owner [he made no
mention of there being any trouble with the hood, even when asked
specifically about any front damage]. No big deal, as it's a really
professional job, if it was in fact repainted.

Externally, the tires and wheels look great -- plenty of tread, and it's
the eight-hole wheels, which look really good on this car and color
(dark grey finish, with lighter gray interior). Very professional
looking. Suspension seems to work well -- one hardly notices cornering,
and speed bumps feel smooth and barely noticeable. Definitely has a
luxury car feel to it.

The guy wants $8,500, but he said he's willing to deal, and is willing
for my mechanic to examine it. I can probably talk him down to $5-6k,
which seems a bit more reasonable.

I like to consult with my father as a mentor in things involving Large
Sums of Money. He says that having 198k on it is too much, and that it's
going to fall apart at the seams. I didn't get a feeling for that at all
-- everything seemed to be in top-notch working order. It sure looks
that with regular maintenance the car could definitely make it another
200k, but I'll leave that to the qualified judgement of my mechanic, who
has a great knack for estimating such things.

Then again, my dad says that if someone offered him the exact same
Toyota Avalon he owns today, with 100k miles, service records, service
performed at regular intervals, he wouldn't take it simply because of
the miles on it, even if offered for a reasonable price. My folks are
very much in the "buy something new" category, and rarely if ever buy
used anything.

As an econ major way back in college, and as a marketer for 27 years, I
trust my dad (and my mother, who also was an econ major and a VP at a
major bank for several years) with financial information and decisions.
Neither of them are remotely mechanically inclined, and certainly not
familiar with cars. Thus, they tend to immediately reject things they
don't understand.

It's my impression that Mercedes diesel engines can run in excess of
400k if maintained regularly. This car appears to be an exceptionally
high-quality vehicle (and I like the 1992 body more than the 1980s-type
bodies), even with 198k miles on the clock.

I have a few pictures, and can make them available upon request.

Any comments, anything in particular for to be concerned about with the
1992 series of diesels? This one has a distinctive luxury-car feel about
it, and seems to be running well.

Thanks again to all for your help.

That is a W124.

That can have different reasons.

A _quick fix_ is to remove the warning light
(little bulb) from the instrument cluster...  ==:-((

That is no fake-wood, but real wood (very thin
verneer, then covered with clearcoat).

You can even get it new from Mercedes.

If cold it has to stay at maximum (3 bar) in idle.

The warmer the oil gets the lower gets the needle -
1 seems a bit low to me, I'd expect 1,5.
But this also has to do with environmental
temperature and oil thickness as well as oil
age.

> and that the temperature gauge seemed a bit low, (~60C), even after 15

Yes, seems a bit low to me, I'd expect ca. 80 C.

However, the W124 suffers from different problems
than the W123, typical W124 problems are:

- Sunroof not working (properly), needs new switch

- Ignition lock not working smoothly (wears relatively
 fast when the car key is on a ring with heavy other
 things)

- windshield wiper system working too slow, which
 means worn which then means many $$$!

- radiator necks made from plastic(!) may break,
 loosing water can mean engine dead

That would also explain the changes headlights

So look carefully on the car's front (and in
engine compartment and also below car) for any
signs of accident

Rear axle is a relatively complicated design -
the arms can wear out, have their rubber bases
checked

Have your mechanic car checked _thoroughly_!!

I'd let him do a cylinder compression test, too:
With new diesel engine the figure should be
465 psi, minimum should be 260 psi.

Not living in the US I can not comment on the price.

Yes, if in doubt trust your mechanic.

I once drove a W124 300D NON-Turbo (109 PS) for a
year or so and it had engine and auto trans overhauled
at ca. 550.000 km (ca. 325k mi) but was heavily used
before

The point is buying new avoids the typical problems
one can have with a used car but of course it is
_much_ more expensive (depriciation).

But have a look into the trunk of the Mercedes W124:
The trunk lid hinge springs have two holes - In case
ever the trunk lid hinge springs weaken you can move
them from the one hole to the other (to hole 2, it is
closer to you if you are standing behind the car -
personally I have never sean any private owned W124
where it was necessary to change from hole 1 to hole 2).
And now look at your dad's Toyota Avalon, which has
gas shock absorbers for the trunk - these will fail
after a certain amount of usage, means you have to
buy and install new ones (ok, typical 10 to 15 years,
but...)

Which is natural (and of course I myself am not
free of that).

Here in Europe the W124 diesel engines were a system
(engine family OM 60X):
4-cylinder non-turbo = 200D
5-cylinder non-Turbo = 250D (200D engine block simply
                            lengthened by 1 cylinder)
5-cylinder Turbo = 250D Turbodiesel (turbocharger added to 250D)
6-cylinder non-Turbo = 300D (200D engine block simply
                            lengthened by 2 cylinders)
6-cylinder Turbo = 300D Turbodiesel (turbocharger added to 300D)

Since the mid-eighties and for more than a decade W124
were _the_ Taxi cab standard in Germany (and in other
European countries, too) and some of them collected more
than 1 million km (600+k mi) without engine and trans
overhaul (and just yesterday I noticed on a major taxi
stand that there were still some W124 around).

> high-quality vehicle (and I like the 1992 body more than the 1980s-type

In a number of ways (rust, passive safety) the W124
body is superior to the body of the predecessor W123.

Can you put them somewhere on the net?

When the W124 series started it suffered from a wide
range of problems - over the years this got better
significantly and from the 1999 models on the quality
is what one expects from a Mercedes.

Heh. That would be bad...the light comes on normally when the car is
started, but is supposed to turn off shortly thereafter, right? If he
just removed it, then it wouldn't light when started. Also something I'd
have the mechanic examine.

Oh, /really/? That's excellent. Any idea how much it would cost to
replace the bit around the ignition?

Well, maybe it didn't get as low as 1...maybe 1.5, I suppose. I just
wasn't sure if the fluctuation was normal.

The owner mentioned something about how would could adjust how much the
cooling system worked, depending on local climate. Presumably in colder
areas, you'd want the engine to run a bit warmer (relative to the air
temperature), and in warmer weather you'd want it to run cooler. I have
no idea about this...that's beyond my realm of knowledge.

The sunroof worked fine, both forward-and-back and up-and-down. I made
sure to check.

Didn't notice any problems -- he just had a little key-fob made from

Didn't test them. It doesn't rain much in California, so I can't imagine
it'd wear that much.

I didn't notice any flaws, but I didn't do a real up-close-and-personal

Agreed. There didn't seem to be any damage, and the bumper had the
original finish. No damage at all anywhere in the engine compartment. I
didn't even notice any difference in paint -- is it possible that it may
have differed ever so slightly from the roof color after 200k miles of
covering a running engine?

I fully intend to have the mechanic check it out very thoroughly. If I
could offer a little bit more for an even MORE thorough check, I'd have
no problem.

Me neither. I just try to avoid making judgement calls when I have
little to no knowledge on a vehicle or situation. I'll seek out the
counsel of others (such as those in this group), do research, and
examine things personally before I'll make comments.

He's under the impression that any engine that reaches 200k is
worthless, worn out, and should not be trusted at all. One of my army
buddies, who knows a lot about diesels said that with a turbo-diesel
properly maintained, it's not uncommon to get more than 400k miles, and
in some cases double that out of them. This car appears to have been
properly maintained in all respects, with only the most mild of
scuffings on the plastic parts of the bumper, which is normal for a car
of that age and not a problem at all.

Hmm. He said that it was a five-cylinder, and I could clearly see the
turbocharger and the air intake on the front-right for it. However, it's
listed on his AutoTrader.com listing as a 300D. Hmm.

Certainly. They are available at the following URL:
http://photobucket.com/albums/y170/heypete/Car/MercedesMenloPark/

Alas, I didn't take more photographs as the battery was low.

I've looked on Google for other 1992 300D series vehicles, and the
headlights look the same, only that these seem to have mini-wipers on
them.

The slight swirls in the finish are due to waxing, I'm sure, and are not
noticeable (or offensive) when looking at the car. A combination of the
flash and sun reflecting seems to have caused them to be emphasized. I
cannot discern any damage to the front, nor can I perceive that the hood
is even the slightest difference in color. Unfortunately, my friend only
mentioned it AFTER we left the place...

Hmm. Well, since this is a 1992 with 198k miles on it, can I assume that
most of the bugs have been shaken out, so to speak? If it's survived
this long with the original engine and transmission, surely any minor
issues have been detected and/or resolved, right?

It certainly seems like a high-quality automobile, though I'm curious
about how much maintenance costs would cost me on an annual basis?

NA?

Not sure what that means.

If you look at
<http://i5.photobucket.com/albums/y170/heypete/Car/MercedesMenloPark/IMG_

turbo.

Also, Edmunds.com describes it as a "Turbo Diesel" for that particular
year.

The one picture of the engine is inconclusive because it does not show the
passenger side of the engine where the turbo lives on those models that come
so equipped.  The slots forward of the wheel are not indicative of a turbo.
After the problems with the trap oxidizer on the 1987 300D (W124), the 1987
300TD (W124 wagon), the 86/87 300 SDL (W126) models, MB did not import
another turbocharged diesel for quite a while after 1992.

These models used various versions of the OM603.9xx engine.  The ceramic
trap oxidizer which was supposed to burn up exhaust particulates instead
tended to clog.  MB replaced them and in some cases the turbos and exhaust
systems that had been ruined because of them.  These engines also had a
problem with heads and head gaskets if overheated. That is why my 1987 300D
had a factory crate engine installed at 200Kmi.

Later models use the OM606 engine. Some NA and some with turbo.

Still, except for the hood that looks like a pretty clean specimen. I
especially like that color and that interior.

According to Edmunds.com, the only 300-series diesels in 1992 were
turbocharged diesels. There is no mention of naturally-aspirated diesels
on their site for that year. Similarly, the owner of the vehicle pointed
out the turbocharger, and said repeatedly that the car has a turbo. My
diesel-savvy friend also confirmed this.

Hmm. Something more for me to look at. Interesting.

*nods* The color and interior go really well together. The car looks
quite classy and very well-maintained. I'm trying to negotiate a time
that would work for both the seller, myself, and the mechanic for an
inspection.

Assuming the car's been properly maintained throughout its life, do you
think it reasonable to expect another 200k miles out of this vehicle
(total of around 400k)? I wouldn't mind buying a high-mileage vehicle if
it is well-built, well-maintained, and will last for years to come.

I stand corrected.  See:
http://home.hiwaay.net/~gbf/mbmodels.html
Note that MB resurrected the 5 cylinder OM602 engine with substantially less
power than the OM 603 engine.  OM603 in 87 produced 148HP vs OM602 in 92
which produced 121HP.

I do not have the W124 part number for a crystal ball. YMMV.  The car will
have many issues other than just the viability of the engine.  Front end,
AC, transmission, steering box, wheel bearings will likely go before the
engine has a problem.  You then have to make an economic decision long
before the engine is an issue.

Indeed. The owner says the AC needs to be recharged a bit, it blows cool
air, but not cold air. Not a big deal.

As for the rest of them, I would assume that a qualified mechanic would
be able to identify potential problems before they occurred and alert me
to any mechanical issues like that...or are some of these parts in
sealed, non-inspectable units?

Cheer!

Because of your quote:

" The owner says the AC needs to be recharged a bit, it blows cool air,
but not cold air. Not a big deal."

Maybe you should take a look at the climate control service manual for
the car in question.  Mercedes cars are not simple and problems like
the above often are a bigger deal to resolve then you might imagine.

If you were satisfied with the feel of your Honda,  you don't want a mercedes.

I will, of course, have the car inspected by a competent mechanic. The
owner of the vehicle indicated that the air conditioning works (and it
does), but that it likely needs to be recharged.

It may simply need a recharge (it has, after all, operated for 13 years,
perhaps not continuously, but still), or there may be something more
serious. Only a detailed inspection will determine that.

If I /were/ satisfied with my Honda, I wouldn't be considering a
Mercedes. There are numerous reasons (which I've listed previously) that
lead me to want to sell the Honda and buy this Mercedes. The fact that
the Mercedes is a solid, reliable, and robust vehicle is among those
reasons.

>From a reliability stanpoint, I'd take a two year old Honda over a 13
year old MB with 200K miles on it any day.  Don't get me wrong.  I have
a 1980 300SD with 115,000 miles on it.  It's been a great car.  But
there is no question that the typical two year old Honda is a more
reliable car than my car or the one you're looking at.    As I pointed
out before, there are various things that just start to go on these
cars over time.  For example, I went to Europe for 2 weeks and left the
car parked at JFK.  It was super hot weather much of that time and when
I returned the dashboard clock which had worked perfectly till then was
kaput.  I think it's likely the heat got to it.  Now in my case, I work
on cars myself and I can pull the dash cluster, find one on ebay, and
replace it, so it won't cost too much.  But how prepared are you to do
that?  Or will you just leave it not working and be satisfied.    Or
will you take it to a shop where it could cost quite a bit to have it
done?

As someone else pointed out, the AC leak, is a good example.  It could
be a simple fill valve leaking.  Or it could be the compressor.  Or
even worse, it could be a leak in the evaporator buried in the dash.
The guy told you it needs recharging, but that could mean once every 3
years or 3 times a year.  The point is, all kinds of little things can
start to go with a 13 year old 200K car that can make it annoying, even
if the major components like the engine, drive train, etc. are still in
fine shape.

I'm not saying don't buy the car.  I'm just saying if you're coming
from a 2 year old Honda, you may be in for a big disappointment,
depending on what your expectations are.
Dori A Schmetterling - 23 Aug 2005 18:51 GMT
Yes.  I am great Merc fan but I don't think I would recomend trading in a
two-year old Honda for an old Merc either, even taking into account the
drawbacks of the Honda.  If I really wanted to be shot of my Honda I would
look at something newer.  In the US you don't have the option of an A-class,
but what about a C-class.  Or another brand?

The newer vehicles are out of my price range. I'm limited by the amount
of money the Honda would fetch.

I don't know much about the dozens of different classes and models of
cars on the market today. I was looking for an affordable diesel,
preferably made by Mercedes (they make excellent engines), for less than
$10,000. This particular vehicle happens to fit my requirements nicely.

In addition to logical reasons such as finances, reliability, etc.,
there's also the abstract concept of physical appeal: The 300D looks
/stunning/, at least to me. It's a very classy-looking car, and has
substance to it. Far more than any modern car (even modern Mercedes)
like a Honda or Toyota. This has some appeal to me.

That said, I try to place most of my decision-making votes on the
"logical reasons" instead of the "Oooh, Shiny!" factor.

Even if there's some parts that have to be repaired or replaced in the
first year or two, I consider myself to be ahead of the game -- the
Honda, while being mechanically reliable, has been very expensive to
keep in good repair due to repeated body damage (only one minor
fender-bender was my fault), scratched paint/finish, and sensitivity to
road conditions like rocks and other small debris. I would much rather
have a vehicle that I could replace many parts myself, rather than
having the car taken into a professional paint-shop to paint it well
(something which I lack the knowledge, skill, and equipment to do).

> Or talk to Bill Ditmire if you are anywhere near New Jersey:

Sounds like the place to go if I were there. Alas, I'm in California, on
the opposite side of the country.

If it's something relatively simple, like changing out a clock, not a
problem. I need to replace the right power mirror assembly on my Honda
-- after a low-speed impact a few months ago, a critical part broke and
fell off. Now the whole module needs to be changed.

For something exceedingly minor (i.e. a minor lightbulb burnt out, and
has no real status associated with it), I could live with it. No big
deal.

For major things, I'd definitely take it to an expert. I'll eat humble
pie and know when something's out of my league.

Good point. Something I'd ask the mechanic about -- perhaps he could
look for a leak, or what? Maybe the owner hasn't recharged the AC in
several years and it simply is time for it? I'll find out soon.

Completely understood. I am expecting a comfortable, reasonably powerful
car with a backseat and trunk (which I currently don't have). The car
must run on diesel. If I can get 50k-100k out of the car before it goes
kaput, I'll be satisfied. That's 2-4 years of driving for me. I'm
looking for a vehicle with a strong and rugged body and frame. There's a
zillion little paint chips on the Honda from the most infintesimal of
impacts. Having to repaint my vehicle every 4-5 years is absurd. The
Mercedes paint has survived 13 years, and still looks better than my
2-year-old Honda.

I want a vehicle that I can do some tinkering with under the hood
without fear of violating a warranty. If the car needs new injectors,
then I'll go to the auto parts store, buy the right ones, and put them
in myself. New fuel filter? Same thing. With the Honda, there's too many
electronics and components packed into an extremely small engine
compartment. With the Mercedes, there's well-defined parts in a large
compartment with easy access. I should be able to handle most of the
minor work.

I think for about $5000 you should be able to find a very, very nice
300D with MUCH less then 250K miles.

I am driving a 1986 190e for over a year now, which set me back about
$2700. In addition I needed tires ($400), serpentine belt tensioner
($75 from boneyard), and various regular maintenance stuffs ($400?).

The car feels very solid on the road and has performed flawlessly for
me.  I have no regrets about buying it, or paying quite  a bit IMO for
an older vehicle.  It had 107K miles on it at the time of purchase, and
has about 120K now.

My car still has some minor issues (left rear power window, spotty AC,
door panel warpage etc.).

These are not issues to me for the most part, although if I find time I
do hope to rectify some of them...

Don't rush into a car.  Look for vehicles that are being sold by
private owners.  Find an owner who you like and get the idea they
understand and care about service.

Good Luck,

Does anyone here have any idea how much ongoing service and maintenance
of a Mercedes is?

Specifically a 1992 300D turbodiesel with 198k miles, as mentioned
earlier in the thread.

Assume no catastrophic engine/transmission damage is present and the
vehicle has had proper service at the designated intervals. I'm looking
for information about ongoing service, such as oil changes, filter
changes, etc. in an attempt to budget myself to have an adequate amount
of money available for maintenance for at least the next year.

Can some of the work be done at home without too much trouble or mess? I
don't mind turning wrenches if it'll save me a few hundred bucks, as
long as it's not something too major.

Cheers!

No, but I need a more practical private car
for in-town driving, a station wagon which
also blends better into any situation and
social environment than e.g. an MB E-class
wagon of the late W210 or even W211 series.

So maybe I will change the W123 sedan for
a - yuck! - Volkswagen...

No, the other way round: Too expensive (looking)
for certain areas of the city, too much vandalism
and theft.
A thing (note: I said _thing_ and not _car_... ;-)) )
like a VW Golf blends in much better there.

Ever driven one?

Had a 147 JTD (1.9 l turbodiesel) for two weeks while on holiday in Italy
recently.  I had had one last year, so I asked for it again.

Mind you, I am not sure I would like to own one, what with its still
slightly iffy reputation for reliability.

In my eyes the 147 is the prettiest in its class, and the larger estate is
one of the most attractive in its segment.
