I ended up selecting a near-mint '02 C32 over an equally pristine '04 M3 SMG after driving both back-to- back...twice. The C32 is such an interesting car. It's interior space is very functional seating 4 easily and comfortably. It's styling. Just technical enough and different enough to set it apart. And finally, it's performance is eye opening if you pay attention - what I mean by that is the super-charged 3.2 is sooooo much smoother than the M powerplant in the M3, that unless you are truly aware of what's going on, you almost take it for granted. I would have given it a 10 in every category except it's features are almost overwhelming. The fuel economy scores low - that's my foot.
Engine. Transmission. Brakes. Seating. Leather. Fit and finish. All top notch.
More intuitive controls. Slight more growl in the exhaust note.
