I ran a GT-R on the track today. It is nothing short of incredible the bang for the buck that this vehicle offers. It certainly is the easiest to drive close to the limit with the computer/electronic help. That being said, unless you're a pro driver, the GT-R will allow you to do things that you will be unable to accomplish in other supercars.
Followed it up with a Murcielago, Italia and 430 Scud. The GT-R doesn't have the exclusivity of the Italians, but omg does it perform like them!
