I like Bimmers. I used to have an M5 with a manual trans and some Dinan and Hamann mods. Got it up to 170mph once. My brother just got rid of an '08 M3 that he modified some and it drove great. He also currently has a track car that started out as an old e30 3 series, but he gutted it, caged it, did suspension, brakes, racing mods, etc and dropped an LS1 Corvette motor in it. He's beat new Z06's on the track in races with his Frankenstein Bimmer.
