Should be a 2000 or 2001. The S4 wasn’t around from 1995-1999.
It actually does handle quite well, and the only weak points (slightly too much roll at the limit) can be easily fixed, unless you factor in that the car is somewhat overweight. The weight is very worth it though, you should see how tank-like the chassis is…plus there is a price for all it’s features and safety etc. Anyhow, the 2001 added ESP, which can really help handling at the limit, depending on what you’re doing. The AWD can give you a little extra confidence going into turns as long as you’re not stupid.
Chipped, it makes 305-320bhp and 360-380ft/lbs, at like, 2000 RPM’s lol.
The only real downside to it all is the fear that your turbos could go at any minute apparently, especially if you’re chipped!
