You come to a Nissan forum and expect anyone to say anything other than the Z? hope not.
Dollar for dollar, in 1991-96?, the 300z was one of the top 3 sports cars in the sub $50k price range. The twin turbo Z was compared to the Corvette, not it's little brothers. Think the Z might have even run with a 911 in one comparo.
Don't let some big block mullet-headed freak talk you up about the 'stang or camaro...Go with the Z and enjoy your ride.
Side note, if you're on a tight budget, then the two domestics should be the only two you consider. 90's Z parts ain't cheap
On the other hand, they'll probably break parts 3x as often as the Z.
