GTR's are too fast, too stable, and too automatic for most streets imho. hense why i did not get one. at minimum it needs a 6MT gearbox for street drivers like me.
i think even the 370Z's are a tad too powerful at times for the streets to really have fun in. but thankfully the Z's dont rev very clean up high so i like to keep the rpm's below 6k for most driving.
