I've got a chance to drive the 350Z. It's an okay car IMHO. Definatley not as torquey as the SC and *feels* bulky. Sure if I had the money I'd but one in a minute! I would also take into consideration the Mazda RX-8. Kinda similair in power to the 350Z but it feels easier to drive. The rotary engine is pretty cool too. I'm sure Nissan reliability is great, but according to the dealer, the 350Z has the same 3.5 litre engine in it as the Altima. It's still a fun car to drive though. There was a thread about the 350Z specifically here a while back if you want to do a search. Good luck!
