25,000 mi on my '08 M3. the only issue if the motherf@ck!ing oil cap- the thing leaks [i actually took it to BMW while still under warranty and they refused to replace the cap with an '09 or later version - apparently, in their estimation, the cap was not in fact defective - it was simply a matter of "allowing the rubber seal to fuse to the neck."] whatever. it still leaks.
is the updated cap available online somewhere? i should just buy it myself.
otherwise, it runs perfectly. i like to think that the '08s were built a little more TLC that the later models - the car has survived the sh!t roads of NYC and LA without producing a single rattle, creak, or bell. still solid as a rock
