Nothing is perfect. And you're right about those rear strut tower failures, but i think they're more common on the m3 (got a friend who just dealt with that issue). I still had driveshaft vibration from bad u-joint, my secondary air pump was throwing a code, the window frame sliders kept breaking, active stability control was tripping a light, but that's all common stuff. Stuff I didn't mind fixing, but just don't have time until next summer, so I figured I'd let someone else deal with it now and I'll get what I really want next year.
