My family has owned Audis since a 1975 Fox. That was a good running vehicle that lasted many years with no major problems except rust.
previously owned Audis:
1975 Fox auto
1973 Fox stick (bought with dead engine)
1978 Fox stick (had to repair rusted gas tank)
1980 4000 stick 4 speed
1884 4000 auto
1985 Coupe/GT auto
current Audi vehicles:
1983 4000S stick 5 speed (owned since 1991) still running very well after 226K miles. Needs a new steering rack since it is leaking. I had installed a VW GTi engine in it when I bought it back in 1991 since the original engine had a wrist pin knock. Both vehicle and engine had 85K on them in 1991 Rust is starting to appear.
1985 5000S (owned since 1985) currently only has 90K miles has needed calipers, window regulators, transmission resealed and sunroof repaired. Headliner is starting to fall down but is running very well with no rust.
I have not owned any recent Audis, but the ones that I have owned have been very good and reliable vehicles. Living in the "rust-zone" usually start to kill most of the early ones. :-( One exception is that Coupe. It was only purchased for the wheels and tires and then sold with it's bad transmission. That transmission seemed to keep working for the new owner though. :-)
I like my 83 Audi 4000S more than the 91 VW Passat that I own even though the Passat looks newer.
