Is the only thing that important to some people the fact of which proves to be ultimately the quickest.
I can't fathom that at all, surely the most important thing is the experience of driving the bloody thing. Re-read the results in full and see what I clearly did, that the M3 is a very talented car indeed. They knocked the engine in one sentence yet in others reckoned it's harmony with it's chassis was brilliant, the M3 is a class act and the fact that other are quicker neither upsets me or makes me believe I choose the wrong car.
The C63 is quicker in acceleration, the RS4 is definitely quicker in difficult conditions and the IS-F is easily as quick without half the effort but none of these (not even the RS4) can entertain like the M3, or offer the same reward for putting that extra effort in.
