Sports cars to me are street cars. WITH ammenities. I personally think there is a difference between racing cars and sports cars.
You are leaving out 95% of all fast cars on the street.
Ferrari, Lambo, Vette, Viper, Buggati, GTR, 370Z etc................. NONE are sports cars?
You are talking about go carts or racing cars.
I'd move that to at LEAST 3500 pounds these days.
I won't argue that the Camaro and Mustang aren't though.
