By far for the price and the performance you get out of this car , IT IS A SUPER CAR.
Not sure how you managed to say that the car is noisy on the inside in such as to the tranny, but if you have a dual cluch tranny you will hear them shefling the gears, regardless of the car.
On the other hand, how could some one mistaken the GT-R with a 350Z, are you kidding me, it seems that these days any one can be a car critic just by creating their website, and get few hits on it.
This car has looks, power, perfromance, for a price that no other manufacturer has yet been able to dish out..
By the way the R8 that you talked about, fell way way behind the GT-R in performance, 1/4 mile, 0-60, braking and it cost twice as much.
