any more help ?  I looking to buy a BMW 750 or 740

Agree with what John Burns states. In fact, the 750i shares the same
engine with the E31 850i and here's what arguably "the" E31 expert,
Paul Michael Brown, says about that car and the same advice can be used
for the 750:

"in my view, it's a mistake to think that you can buy an E31 and sell
it later for more than you paid. On the contrary, you'll spend serious
money to get the car sorted out, serious money to maintain it
thereafter and you'll take a big depreciation hit when you sell it.

Now if your finances are such that you can afford a purchase price of

$17-22K, plus $2,500 - $5,000 per year in upkeep without losing
sleep.....

If the cost of ownership doesn't scare you off and you still want to
own an E31, the smart choice is to buy a well-maintained example from a
private owner who can provide you with a stack of service records.
Absolutely, positively DO NOT BUY a cheap E31 from a used car dealer
without knowing who has owned the car in the past or how it has been
maintained. Those are the cars that cost $15K to buy, but $10K to
maintain in their first year. You are FAR better off searching the
country for an
E31 being offered for sale by an owner who could afford to maintain it
correctly and who can prove that to you with service records.

If you find an 850i with good service records, look to see if the big
ticket repairs have been performed: water pump, fan clutch, DK motors,
brake pressure accumulator, front end bushings etc., intake manifold
gasket, shocks & struts. It's rare to find a car that has had *all*
these things fixed. (The intake manifold gasket seems to last forever
on some cars, for example.) But a car with several of these repairs
should command a premium because you probably won't have to do them
again unless you own the car for a very long time and drive the hell
out of it.

Then look for certain routine maintenance that is vitally important on
E31: cooling system flush and fill; autobox flush and fill (use of
Mobil 1
ATF a big plus); rear differential lube change (again, synthetic gear
lube a plus); brake fluid replacement. Also note that the E31 has a
central
hydraulic system. Look to see if the CHF fluid and filter have been
changed. Lots of owners never do this and as a result the hydraulic
system
often needs repair. Don't forget mundane items like the batteries.
There are two in the trunk and a fastidious owner will have replaced
them with
quality Interstate models. Check the onboard computer display for dead
pixels. A car with a new unit and a good display should command a
premium.
Exercise the power seats and the sunroof. Often these items have minor
faults. The repair is fairly simple, but you can tell a lot about an
owner
by how well he keeps up with the small stuff. Finally, look for a
recent Inspection II. If it's been awhile, you should budget at least
$2,500 to get one done right after purchase.

(Clearing throat) That's two in-line sixes, not two v-sixes... (duhhh)
there is a difference. It's like having two engines....  no benefit in
that! I can see that you have never driven one.... what's there to
facinate you? How would YOU know? Bet you've never been within 50 feet
of one; thanks SO much for the advice. Blow the doors off your Acura
"exotic"... LOL

Maybe you were looking for alt.autos.acura and got here by mistake...
don't let the screen door hit you in the a.s on the way out.

No whiners!

Buy the 750
drive it like you stole it
fix it when it breaks
and always remember
it's a GODDAMN BMW
feel sorry for all the other drivers
and their sad a.s rides
life is short
and you can't take it with you
nothing good in life is free
and if anything lasted forever
it would be ultimately boring
put on some Rammstein
crank it up
floor it
& tell me I'm wrong
