I guess the reason that everyone keeps comparing the C32 to the M3 is because the 3-series is always compared with the C-class. Unfortunately you can't do it with the M3 and the C32. The M3 is 2-door only and manual transmission only. The C32 is 4-door only and automatic transmisison only. Those two differences separate the two cars into markets that don't have much overlap.

If you still insist on comparing the two, you're going to have to wait a couple months for test data on the C32. The C32 is supposed to debut at the Detroit (NAIA) show in January. Sales are supposed to begin in Europe in March and in the U.S. shortly afterward.
