need some help on 370z ideas

ShinyaPGH

Hi. Newbie on the forum here. I grew up in Japan, dreaming about the fairlady z, so finally, I'm at the point it my life to get me a 370Z. My budget is around 40k. I'm hoping, I can score one for 25k, and spend the rest on the mods.
how far will 15k get me?
Also any recommendations on the tuning shop who is relatively close to Pittsburgh, PA? Less than 200 miles is desirable.
The car will be a weekend car/light duty track car. So, suspension and breaks may be the priority. Good stereo without adding much weight is important to me, too. Stillen Full body kit would be awesome, along with light weight rims. Maybe an exhaust system if there is room in the budget.

A little about me. I used to be a track junkie on 2 wheels, until the injuries kept piling up, and Finally decided to hang it up. I still have a need for speed. Never tracked a 4 wheel other than drag strips, but I'm hoping my motorcycle track background can jumpstart my new adventure.

Thanks for any help!
