I have the money but still wonder if I really need a GT-R... In addition, GT-R is also kind of old now!!!
My next car should still be a performance car and it would be my final and best car in my life... So, I have to put my money on a RIGHT car!!! 
New NSX is good but too impractical for me!!! (GT-R is still much more practical than NSX) In my opinion, NSX should be a little better than GT-R thanks to newer technology. (The numbers are important but definitely don't include everything!!!)
A performance car is not really necessary if you don't race your car with others frequently. However, if you have the additional money, it's not a bad idea to try something among the best in the auto industry!!!
