I've been looking at an '88 5000 CS Quattro in the area. It has a few electrical glitches i.e.: rear window and outside dr handle, power locks, passenger seat motor and heater. The owner has it priced a bit high because she's in need of money ($2500). It's a 5-speed and the mileage shows 165k which is great for its age. I'm wondering how accurate it is. Can anyone tell me what mechanical issues I should look for in this model? I'm unable to test drive it until she gets a temp plate put on it--it's been sitting awhile. It started up alright, but did smell like it's burning oil. I know Audi repair shops are high dollar, but what kind of things should I be looking into before considering a purchase? She is willing to take a few hundred off the price, but I'm thinking she may need take off about a $1000. It does appear to be a pretty cool car. The AWD system is cool and sunroof and most other power features are working. The interior isn't too bad for its age, either. I appreciate any advice you can give.
