Anybody check out the latest Winding Road articles on the Lexus and MB rockets. I think that the mighty M3 may have something to worry about - but obviously we won't know for sure until the head-to-heads are completed. But from the initial reviews, the M3 appears to be behind the group! Winding road went so far as to state that between the M3 and the C63, overall the C63 is the better car. Things are getting interesting.
