Cossie will feel quicker because the way it gives its power out, the M3 does not feel quick because it is progressive. I had a M3 Evo and they really do come on song in third. They surprised a shit load of other cars when they get going, they will go passed a E46 M3 when you start getting to silly speeds and stick with the E39 M5.

The cosworth is a straight line power house that can be tuned. The M3 will do a decent straight line speed, go like fuck around corners, be comfy and take the family out and be safe all under one package. This is what the M3 Does, it is not a master at anything but good at everything. Shouldnt really compare them as they are from different times.

For the record, my RWD Cosworth Escort went passed a 370z like it was stood still, mine is a good stage 3 and lighter than the normal. The guy in the 370z was giving it everything and got blown a new ass hole. I want to try a M3 E46 and then a E90 as I think it would certainly give the E90 ago from 30 to 100mph. After that both the M3;s would rape me
