Before you get blasted there is a search function at the top of the page that you can use and find so much information you will get tired reading it all.
As to answer your questions a better way is to describe what you are looking for in a sports car and allow the good users of this site to better describe the good and the bad for you. In my opinion I love the car but I am bias because I grew up learning how to drive a manual 280zx and had that until I bought the 350z then onto the 370z. I wanted a little more power that is why I supercharged it and now the way it sets and looks is what I want so I could not be happier. Good luck with your search and if a Z is in your future then the future look bright for you young jedi.
