My '99 A4 was reliable for the entire 6 months I owned it. I don't own cars long enough for them to break. Fortunately for me, the previous owner had recently had the head rebuild and timing belt replaced when the belt snapped 14k prior to it's replacement interval. Then the used car lot that bought it had to replace the turbo prior to selling it to me. The beast had been fed, and was satisfied during my ownership. Still, at 100k it very obviously needed a suspension refresh.

David, as for your sister, I don't think you ever really pinpointed what she wants (sedan, coupe, etc). To throw out a few though, I've always really liked the Infiniti G35 coupe. Really great looking cars, fun to drive, nice interior, and reliable. $25k should buy her a nearly new one. G35 sedan is nice as well, $25k might buy her a 2007 (new body style). The M-series Infiniti models are very nice as well. Lexus IS is a nice sporty sedan, the GS is also quite nice but probably beyond her budget. The Acura TSX is another nice sporty sedan, the TL is also very nice.
