I've owned it. Just the typical things like wheel bearings in the 60K-80K mile range is really all that has needed to be replaced. My aftermarket warranty covered it all. It seems that you either get a good one or a bad one. Many S4 owners have gone over 100K miles with minimal maintenance and others have had to replace turbos at 30K miles. It seems like it's very car dependent. I can tell you that I tried blowing my turbos up on purpose and they wouldn't blow up. I have no doubt they would have went well past 100K miles on APR chip without blowing. I think the newer oil lines in the '01.5 and '02 cars may have something to do with it. Maybe it has to do with the oil used. I think a lot of guys have boost leaks they don't know about which causes the turbos to overboost and break. I think there are lots of variables as to why the turbos go. I replaced mine for the fun of it. :-)
