I have very little experience with them personally, but a friend of mine did buy a A4 1.8t Quattro new in 01. The car was mostly stock with F-K coilovers and 18's. It was a nice car quiet luxury car to cuise in (stock) and handled well. It was about as fast as my stock supra turbo and almost as heavy, but it had an excuse (quattro).
My buddy is a tech at a Porsche/Audi/VW dealer. In the summer they get to take a few of the cars to some shows. I did get one ride in an 04 S4, and that car + his driving = one scary F**king ride. It's a totally different animal, all quiet and subdued but stomp on it and it Hauls ass. The brakes are amazing too, imo. He had me scared before I realized this.
I know, I know, it's a 5valve per cylinder 4.2 V8 so not what your looking for, but still, a chipped 02 would probably be a pretty close match:dunno:
This same friend sold his 1.8T a few years ago. He's come back to senses, and is also currently looking for the right 02 S4.
Its one of the first luxury performance cars I'd consider.
(Soarer would be 1st)
