look at weights on older 3 series, the coupe and sedan are at a dead heat for weight.
The M3 will kick butt, and be seriously fast. The bad part is that it's a grand tourer now, old man car if you will...............like a 6 series or an M5

I was told the new alu v8s are actually lighter if not the same weight as the current gen i-6s ?
