the M3 is a true sports car. Stock M3 runs 0-60 at 4.6 seconds. It costs around $50k with 333HP. It's an amazing machine. It also has an SMG transmission (
http://www.turbo.screaming.net/smg.htm) that is out of this world (don't get it mixed up with tiptronic stuff). These guys are nuts about their cars, some have 20-30K in mods in them. This guy paid $4k on wheels only. It weighs about 2700 lbs, almost half of an SSR. So it's a sports car.
I call the SSR a cruiser and I wouldn't trade it for an M3, but would love to have both. Next Spring I may treat myself to one and if I'm good I may get one under the tree this Christmas
