Which one should I get?

350z if you only need 2 seats or V6 Camry S.E..

u cant compare a 350z to the other cars, are u like on crack or somethin?

single? wanna melt guy's hearts? go for the 350Z

Maxima or Fusion.

The Camry has had a lot of problems and the 350 is an sport car.

None. Get the Nissan Altima.

Depends what your needs are.

The Accord will be a cheapest to run (if you get the 2.0L) although they do make a V6 model which will be a little more harsh on gas.

Maxima is a nice car V6 engine with decent power.

I don't know anything about Camry's (must be an American car)

350Z is a sports car, which will cost heaps to buy, heaps to repair when it breaks, heaps to run, heaps to insure. But will get you all the looks and fun as hell to drive.
