I've had the pleasure of driving a lightly modified 300zx TT a while back but that was the first "fast" car that I had ever driven (i.e. 300+hp). It was a blast to drive, loved it and wish my brother never sold it. Soon after I had the itch and bought my 350z, which felt a bit slower because of the linear power delivery. And of course now I have my 370z.
I really wish I could drive all 3 cars back to back. The last 3 generations were all awesome cars, but IMO, my 370z would edge out the 300zx TT.
