Everybody is saying that its light years ahead of any other previous GT-R - OK, gimme 170K, and I reckon that I could buy and make the R34 GT-R V-Spec II Nur annihilate any R35 GT-R, modded or not.
Seriously people - with R35 extra weight I do believe that lighter, modded R34 would be better.
Then of course, you have to look at the cost to modd the R35 - 20K, 50K, where is the limit. So you will end up with the 250K car, and I do reckon that a tuned R34 would still be better - 200kg less weight in stock trim is alot of weight to carry through corners.
