I actually own a C6 right now and my bro owns an e46 m3

Let me try: SPeed/HP wise the corvette wins hands down no comparison here, the corvette just punishes the m3.

Handiling wise you would think the bimmer was better but i still think the c6 does its jov well

now as for the m3, its a whole lot more comfortable inside. idont mean its like a soft cadillac ride, i mean its just more user friendly and im able to settle down and cruise with it one minute then bust it open another minute. the vette just isnt like that at all. Even though the m3 is down on power vs. a corvette, i think the m3 is a much more usable car in real life. thats the reason im switiching to a bimmer next time around. after reading that there is going to be a v-8 in this new m3 well maybee it will still be a sweet ride but be able to go as fast as the c6 tooo
