Developed starting problems that the dealer has been unable to sort out.
Odd electrical problems such as boot light switches, mirror switches and door switches sticking or failing.
Not bad, since it's a company car I guess the dealers bend over backwards to help so can't comment on normal service levels.
We bought a '95 2.6 80 twelve months ago with 153000km on the clock from a euro tuning shop, and it was, and still is, in stunning condition with no signs of wear anywhere.
It has performed mechanically faultlessly for the 10000k's that we have owned it. It has had some electrical issues like temporary power window failure and various instrument panel warning lights coming on despite no apparent problems.
But to drive these thing is a wonderful experience. It handles like a dream and goes pretty hard. These cars are the best Audis ever.
I spent a lot of time doing the sensible thing looking at Camrys and Corollas and found them very boring. Decided to pursue a car that fitted my penchant for german cars and instantly found these cars to be so much more attractive (a) to look at, and (b) to drive! They're inherent safety is just a bonus. (these things are solid as rocks).
Obviously I cannot recommend these things highly enough. They are now very cheap and a very good car for a mum or dad to put their kids in for their first car. GET ONE!!!
