The General wasn't bluffing when they said the Chevy Camaro might out-perform the 2010 Mustang in early summer sales. The Camaro was the best-selling muscle car in June by more than 1,000 units.

Building on the excitement over the new car, no doubt helped by Transformers: Revenge of the Fallen, the Camaro achieved sales of 9,320 units, compared to just 7,632 for the Mustang. Could this be the start of a trend?
