I remember reading about this particular model of M3, known as CSL. I skimmed through a road and track magazine that talked about it. I remember it saying something about being made out of lightweight material that is suppose to reduce the gross weight of the car. Other than that, is there anything else special? I noticed the body is identical as the current m3 models. On another note, do you guys think the current M3 body style should change? Personally, I don't really like how the new model bmws are looking. It's losing it's traditional style that I have grown fond of. IE the new 7 series. Personally, I think they should stick with the current body design. I like it a lot. :driving
