Actually, it's the M400 which is slightly different than the M12 GTO3R. The M400 designation is because it has 400 HP / Ton of car weight. It costs a little over 10K more than the M12 GTO3R. You get a better handling car, more power, better seats, better shift linkage, worse ride, no AC. Most would say that it is a better track car than daily driver, especially if you have bad roads like in MI. Overall appearance though is pretty much the same except for the side scoops. Tim
