Coming from Type-R ownership, Ihave found the Z to be more of a grown-up kind of car, its a "look good, going slow" type of feeling, I dont get the urge to plant my foot into the Mat, whereas, in my CTR, it had that RAW, RACE feel to it, an edginess that made your hair fizz and really go-kart like handling, which I daresay, would out-handle a Z on track around the twisties.
Is the Z quick? Yes it is, but in a civilised, controlled manner, the difference is, it doesnt look like youre trying too hard
