I don't know - I appreciate the engineering, the creativity, and the performance, but it just doesn't have the gestalt of the M3W.
For me, it's sort of like those Goldwings with the training wheel rears, I'm sure they are pleasant to ride, but seem to be neither fish no fowl. I'll take my 12yr old Lotus Elise out to carve corners all day. and the M3W when I want to do some serious motoring! Neither pretends to be like the other.
