I got better fuel economy from my C63 than I do from my M3.

But then again, my M3 does not need new rear tires every 5,000 miles.

The IS-F is an excellent compromise between the M3 and C63 and will most likely prove quite a bit more reliable than those cars. Only major drawbacks that I see are the smallish interior (would be better without a sunroof) and the 8-speed tranny (one too many gears).
