i love the 300zx and the 350z. although the 350z is a great car, i would lean to get a 300zx tt. the 300zx's design is timeless, well, so is the 350z, but i like the 300zx better. lets put it at that.
other than the z's, i would definitely take old school. the evo, sti, and rx-8 are all four-doors, what the heck. and the srt-4 is fwd, what the heck. i believe that the new "sports cars" are going downhill. they might be getting faster, but c'mon now, four-doors and fwd? good thing the z car stayed with the 2-door rwd layout.
