Taking on Gran Turismo 3, and All I'm Using are American Cars

Due to unknown reasons, I was only able to race in Gran Turismo in American cars. Can this competition be won without using cars from any other country? Special thanks to Gtafan in GTPlanet for the Retexture MOD, as well as the Grand Theft Auto 5 modding community. For without them, this video would be impossible to make.
