Totally randomly passing by this thread and I am sure to get a lot of flack for this, but since I saw your post, I had to ask why not A5? Other than crazy/smooth acceleration, what exactly does an M3 have over an Audi A5? Comfort? luxury? Build quality? None of these imo. Heck, the damn thing doesn't even have power liftgate. Audi's infotainment system is awesome (apparently) so it's not like a cheap plastic touch screen with beach buggy support beats that. I recently sat in an A5 (have a Model S myself) and the build quality is astonishingly better than even the S, let alone 3. Some people want that a lot more than just acceleration.
