Too expensive, too big, too soft, steering too light. Clutch is way too light and travel sucks, the shifter is clearly an afterthought with poor throws. Maybe these weren't a big deal but for my monthly payments it was getting a bit annoying. I miss the engine, but that's about it. Loving my E36. S/C goes on this week. But the car I miss the most is still a bone stock E46 M3.
Caveat: the track in my city went away. So without a track, the E9x M3 is slightly less justifiable.
