Neil I know what you mean with the 370z That's a blast to drive. I had a 2006 G35x & it had the same drive train as the 350z except it was AWD & it was a beast on a 4door frame so I can bet its a screamer in a 2 door format. plus its the drive train for the modern day Skyline (Infiniti G Series). Only reason replacing the G35x is that it was totaled by a drunk. I will say I love my XK, but can't beat time in a performance car as well.
