News flash: There have always been base model cars and high performance model cars with the same looks. In fact, I can't think of very many cars at all that don't have a 'slow & econimical' version.

Acura Integra RS to Acura Integra Type R
Subaru Impreza WRX to Subaru WRX STi
Mitsubishi Lancer to Mitsubishi Evolution
Corvette coupe to Corvette Z06
BMW 5 series to BMW M5
Toyota Supra (NA) to Toyota Supra (twin turbo)
Mustang (V6) to Mustang Cobra/Saleen

Get used to it.
