Thinking about buying '90 Coupe Quattro

[cwhanlon@eai.com]

Hi all, I'm thinking about buying an Audi Quattro.  Today I'm
going to take a look at an 1990 Coupe Quattro w/ 96,000 miles.

Are there certain things I should look for that often go wrong?
The car is due for a timing belt change.

I'm also worried about the mileage.  How many miles do the
20 valve engines usually last (I know, not an exact question,
but I don't expect an exact answer :)

Also what is the engine size and horsepower for this particular
car.  (and any other specs such as weight)

THanks!!!!
