That is debateable that those vehicals are performance cars. I am not claiming that a skyline is a performance car either BTW.
Porsche, Lamba, bugatti etc are performance vehicles, truely designed for the sole purpose of performance and speed from the ground up.
The skylines and FPV, HSV's, EVO's, WRX are still based from mass producted factory vehicles with some bolt on goodies. They are essientially designed for your everyday market, not a true performance vehicle.
Mustang, Camaro, Cobra, Viper. Performance designed and breed
Monaro is the only car that can claim to be anything close to a performance vehicle but a Monaro isn't badged as a commodore is it
