The 350z is alot of fun to drive. The trans is VERY clunky and awkward though. If you test drive one and it's grindy and clunky don't worry. They are all like that. You really have to muscle it into gears.
lol I believe you, thats not the first time I have heard about that
It also makes ALOT of noise when the car is at idle. That is normal too. It is a robust trans though. Mine handled (with upgraded clutch/master cylinder/clutch fork) 500whp in my G35.
