2012 CHEVROLET CORVETTE COUPE GRAND SPORT 2LT for sale in Inferno Orange has me puzzled. There are badges right above the Grand Sport badge that say "Turbo Edition". Dealership cannot tell me what that package consists of or where it came from. This is a Cadillac Dealership that has the car and they can't tell me much about the care except that it has less than 2k miles. Anyone know what Turbo Edition consists of besides a possible turbo?
