The Lotus Exige S would give this a run for it's money and the GT-R has 245 HP+ on it.
The Vette's "stock" have NEVER been good track (by track, I mean a Road Course with a lot of turns, like Laguna Seca) cars. I'll never understand why some think they are. Vipers aren't even that great "stock" on the track either. The Ford GT would give it a run for it's money as well on the track.
IMO, the Skyline will command too much money for it's worth. This car will not do good in the US sales wise, supposedly it becomes available here in June. I still say the Z-Tune was a better car than this. But, that's just me.
