Ok so the GT500 is a warmed up GT. That makes the Z06 a warmed up C6. That makes the Porsche GT3 a warmed up 911 Turbo. That makes..... Every "special edition" or "performance edition" car is just a warmed up version of the base car. So what? Aside from looks, each of those cars drives and acts completely different than the base model it's based off of.
