its a cycle.... Gm dominated the muscle car industry for so long. When bankruptcy and money troubles hit GM, thier money was spent on research and development on "green" technology. The problem with the gt500 is that its still on a mustang platform.for the kind of money your going to spend on it wouldnt you want a more refined sports car like the corvette? My opinion on the Gt500 is that it is no more exclusive as a srt4. sure it will perform with the best, but at the end of the day its a mustang. Im not sure of the msrp of the zl1 but if its anywhere close to the gt500, i would still advice chevy consumer to opt for the vette. why? vettes make em wet
