My comment about the z06, viper, and gt40 are based around your statement that the US has no sports cars. I didnt realize by sports cars you were talking about grocery getters. My mistake. You were refering to camaros, mustangs and the such, which arent sports cars.
FYI the Jap sports cars were priced in the same range as the corvette. And by sports cars im talking about the 3000GT, Supra, RX7, 300ZX. Japan hasnt sent a sports car to the US in some time now, and no the 350z and rx8 dont count. The new market is the grocery getter turned into a rally car.
