2005 Ford Mustang Road Test

If the Viper is America's supercar and the Corvette its sports car, the Mustang has to be America's GT, despite Ford dubbing its first blue-oval branded supercar in decades with the name. Even Camaro and Firebird fans can't dispute such a claim now that both models have been discontinued. No, the Mustang holds the GT title based on its 40-plus years of service and absolute dominance in the market.
