Alright, alright, time to put this to rest.
I just sold my modded Evo X GSR to get an E92 M3, and am not regretting it one bit. Like what was said before, if you're interested in just pure balls out performance and pretty much nothing else, get the Evo. It's a great car that responds well to mods, is relatively cheap to make decent power, and it kills on the track. (search Ryan Gates Evo X for examples).
