I had a spin in the GT pack 350, really nice car, lacks a bit of low down torque which you wouldn't expect from a V6, in the 370 they've flatten out the torque curve and its supposed to be a lot quicker, also 100kg lighter than the outgoing model, which is very rare these days.
I think Nissan have really turned the brand around, they are the only JAP now offering a genuine sports car( 2 door rwd) now...I was looking forward to the new ae86 from Toyota with the STI running gear but with all Toyotas recent problems I would guess that will be shelved for a while
