i had the GT-R before my M3 and all I can say is what a car...
The GT-R can make any driver seem like Michael Schumacher on a track its unbelievable. There were very few cars I couldn't pass on a track, and I actually sold it because it was like driving in a video game. Its so easy but it lacks the effort..and the effort is what makes it fun.
I also missed the sound of a V8...so I went back to an M3, something that requires a little more skill and diligence to get around a track.
I may get the new 911 next...
