The clutch can be a definite issue despite the fact some here may have not experienced clutch problems. BMW will not warranty a clutch replacement solely due to wear and slippage. They will warranty an RTP clutch for slippage one time. Another surprising fact of life, at least for me, is the fact there are LEO's that get involved with RTP's having had no experience with a clutch on anything. Some of these officers have never driven anything without an automatic transmission.
