Judging from your profile: Financial, short/long term needs

Buy and 06 350Z and Keep it bpu.

You need something reliable and moderately quick

Generally 06 350z's will run 13's - 05 350z's will do that BPU.
03-04 are cool but watch the alignment issues.

(Remember when running 13's was the shit???)

We all know about the Supra TT. It's obviously a great choice, but will exceed your budget (money pits).
