Thinking about buying a 91 200 Quattro Turbo (long)

[Al Youngwerth <alberty@apexxtech.com>]

Greetings,

I'm thinking about purchasing a 1991 Audi Quattro 200 Turbo (20V 217hp).
It's a 5sp, totally loaded (even got the hands-free Audi phone). It
looks just about perfect and seems to be in excellent overall condition.
Paint, body and interior appear almost new.

It's a two owner car. First owner put on 90,000 miles in three years,
all highway. Second owner has put on 51,000 miles, mostly highway.

I have driven and inspected the car and observed the following:

Pulls to the right, although not strongly. Tire pressure did not appear
to be grossly off.

The temperature gauge does not work.

The Digital display in the dash that tells you what radio station your
on only has lines going through it (although the owner says it works
more often than not).

The engine is dirty but there doesn't appear to be any leaks.

The plastic cover for the bolts on the spark-plug wire cover are broken.

The major fluids do not appear to have been flushed ever (brake,
power-steering and radiator). The brake fluid is dirty than I'd like it
to be (scares me a little on an ABS car).

There are complete service records for the car but I haven't seen them.

Car rides well, handles well, no rattles or buzzes. Engine seems to idle
well (although I think it may have stalled once when he started it after
I drove it). Has a lot more power down low then my friends 89 200 wagon
but doesn't feel quite as quick overall as my 86 SAAB 9000 Turbo.

His mileage gauge showed 18MPG average (he said he'd done mostly city
driving since he filled it up). I saw about 28MPG at a steady 60 mph.

So here are my questions:

Do any of these problems sound serious? I will be taking the car to my
friend's Audi mechanic for a complete checkup (seems to be very
competent). Are there other things I should look for?

What are common problems with this car. What things are unusually
expensive to repair (mostly in terms of parts, I do almost all of my own
wrenching). What do the common failure parts cost roughly.

What's a good price range for the car?

I plan to own the car for 2-3 years and put 40-60K miles on it. I've
never owned an Audi before but have always wanted to.

Thanks in advance for any responses...
