Base models and GT V6 automatics rode on 16-inch tires, versus 17-inch for the GT V6 manual models. Tuscani models had all the upgrades being the "Elite" model with separate badging to set it apart from all other models. Both had standard four-wheel disc brakes. Leather upholstery was standard in the GT V6, as well as a rear spoiler (high spoiler std. on 6-speed only). Aluminium pedals and a sunroof were optional. In 2004, all GT V6s received 17" wheels.
