The Gp is a limited run of 2000 cars. They only come in Thunder Blue Metallic (the only car this color is used on). They have the John Cooper Works package(smaller supercharger pulley, different head, brakes, intake,exhaust,suspension). They come with 217 bhp, compared to the normal 168. Gp's come with these funky wheels, again only offered on the GP's. They have no rear seat, a rear strut tower bar, 2 front speakers only.
