is this your first car? If so what i'd honestly do is buy manual non-turbo (spyder if you want) b/c you'll probably do something, or many things, dumb with it. Its not your fault, we've all been there, myself included. After you're more comfortable, sell the NT and buy a manual GSX or spyder, depending if you want speed or a convertible more.
Personally, I think a turbo DSM is WAYYY too much power for a starter car, esp. one that's been lightly modded.
just my .02 though, if you still have questions about the GSX/Spyder and mods i'm more than happy to help. Most of us on this site have owned multiple DSMs.
