Working at Nissan, I get to drive/drive against pretty much everything that the Nissan/Infiniti brand can throw out.
I agree on the G convertible... My N/A can take one in the straights, and it's no contest in the curvy bits. G-coupe is a bit faster and it's a driver's race in a straight line... still, adios in the corners. Driver mod
I have been beaten by every 370Z I've encountered, no question that they're faster than me in the straights and the corners. Sh!tty brakes on those things though, don't attempt a track day!
The Nismo 370Z, in Metallic Slate/White Pearl, is a jaw-dropper and I would take one in a heartbeat.
