I love them 20Vs vroooom for grown ups.

I have had my saloon for 3 years or more and have put 60,000 miles of
local taxi work on it without a problem,

A puddle of condensation often appears on the left footwell when you run
the aircon. If it's not the AC then it might have something to do with
deluge weathewr we have had lately.

The brake squeak is also common mine did it for a while but stopped on
it's own. The rear callipers are a bit fussy and often play up a little,
having the rear pads changed will almost certainly cure it.

The remote locking issue is a common problem, originaly a paper tag came
with the keys having a 4 digit number on it, most likely lost many years
ago. If you don't have the 4 digit number the Fiat agents maybe able to
supply it from your VIN number, if they haven't deleted it from the
database. This will cost 10 or 15 quid to get the number.

There is a procedure for reactivating the remote locking and alarm
detailed in the Fiat handbook, but without the 4 digit number you have
no chance. You will also find a keyswitch inside the main fusebox that
may have been used to disable the remote locking/alarm but again it is
unkikely you will have the key and most probable it has been switched of
for a reason.

If you look around on ebay there is a kit to add remote locking to
almost any car with central locking, this is often a cheaper and more
sensible way to procede if you realy want remote locking on your car.
These kits sell for about 25 quid.

The window is likely just stuck thru lack of use, have an assistant work
the switch while you manhandle the glass up and down a few times, you'll
probably get it working even if sluggish.

It sounds like you have a good motor and I'm sure you never paid a huge
amount of money for it. That'e the Beauty of Mareas, they are a lot of
car for the money. Just a few things tho to make you think.

A cam belt change will cost a fortune, between 4 and 12 hundred
pounds!!! if you are lucky yours was done already at the 72k mark, if
not don't worry about it cause a secondhand engine is cheaper than the
service.

Bottom balljoints are a weak spot on these cars and fairly costly to
replace, It spoils the handling of the car altogether if the balljoints
are worn and will fail an MOT. Also drop links are a bit iffy and often
knock on uneven roads.

Rust is another problem, the floorpan on some of these early mareas is
prone to rusting, especialy around the rear, get under the car and look
for rusty bits before they turn into holes, a bit of wire brushing and
underseal could save the car from an early grave.

Brake pipes also are worth saving with a bit of wire brushing and
hammerite, replacement is very costly if they rot thru and it's well
worth making sure they don't.

Have fun...
