The gt500 is a nice car for the thrill of violent power, but does not evoke the confidence that the m does on the track. It always feels like your having to work at driving the gt500 and the M3 seams to just know what to do. If I was just going to drive on the street or drag it, I would buy the Shelby or even better the Super Snake. But for the track, well you know........the M3 is just the most well rounded car for 60-70k, IMO.
