Yeah, Porsche territory is sort of...not in the scope of this discussion. And just to clarify, you said Porsche 911 GT. Which model are you actually referring to, as there is no "GT". There's the GT2 and GT3 available currently, there was a GT1, though I don't know if that was street legal or even available in the US. There's also the 911 Turbo, which is the basest of the hopped up models. Oh hell, who am I kidding, any of them would be fine.
