I bought an 04 new. Coupe with SMG. I specifically bought the car for the SMG. Loved the SMG - well, when in full manual mode with all nanny controls turned off! It does these awesome double blips of the throttle on downshifts. If you expect to ever drive the SMG in auto mode (I can't imagine why anyone would do this in a friggin M3 but to each his own), it will be one of the worst transmissions you've ever experienced. Very quick car, easy to drive very fast. Like most modern performance cars, no fun at all until you are double or triple the speed limit.
Had a number of weird electrical glitches that occasionally stranded me
Dumped it before the warranty ran out.
