I'm torn.
I'd go with a Nissan Silvia S15, Nissan Skyline R34, Mercedes Benz SLK55 AMG (I think that's right), or a Porsche Carrera4s (or whatever that expensive motha fawka is). Then I'd just mod the funk outta the suspension, then the motor, and use my own money to go to race car school. Get good enough, and go pro.
