What kind of warranty comes with it? I was looking at 2000-2001 S4s before I bought my current car. The concensus is that the oil feed lines to the turbos are too small and have a possiblity of starving them, then turbos go kaboom. You gotta pull the whole engine to change em, $7K job. It's not like this has happened on a few cars, some are on their 3rd set. But other than that it's fast, looks good, easily modded and it's a luxury sedan. Hang around the Audi forums to learn more.
