I think the conclusion from this thread from my point of view is as follows..
The 350z is by no means the worlds best car, or fastest, something i knew from day one, but it certainly isnt the worst or the slowest. Their are things i love about my 350 and things i would change, but then that would apply to nearly any car that i own.
Its all down to personal experiences and taste, i for one enjoy owning my car and anyone who says they're crap need to have an extremey good reason to say so, either way their will be people who love and hate, but who really cares when its you behind the wheel not them..
