how big is the market for a performance car that costs over $35k these days? or for a $25k car that gets mpg numbers in the low 30's at best? yes, 30mpg is impressive for a car like that, but gas probably won't be getting any cheaper in the next few years.
the Camaro is doing good not only because it's a damn good car, but because it's still shiny and new.
the real test comes in the next few years when we see if sales hold up, how well the cars hold up in the real world, and how it's sales compare to sales of Mustangs and other comparable cars.
