I hate the GT-R in GT5, especially in the online section,
where even the most average driver can take it to the win. Yes, sure, it has understeer due to its AWD nature, but it has such a ridiculous amount of grip that you can rocket it out of the missed apex and still be faster than any other car that took the line properly, and I really can't stand that. In its stock PP range it is untouchable, there's not a single car that can face the GT-R, and it is competetitive against cars that are above its theoretical capabilities.
And then there's the lack of soul. It's an unbelievably fast car, but it's as boring to drive as a Kei car, at least in my opinion. It never becomes unstable, not a hint of oversteer....
Would I take a GT-R in real life? Sure, in fact I saw one this past summer and to be honest the car is quite cool. But I would never take it if I had the chance to get my hands on an old school, RWD, manual tranny Corvette, 911 or Testarossa
