You have $30,000 to buy yourself a brand new car(When I say brand new I mean brand new,NO USED) Any money you have left over can be used to improve/modify the car as you see fit. I would probably buy the Ford Fiesta ST. It's practical, quick and fun. Plus you can pick one up with recaro seats for around 23,000. That's a damn good deal for a hot hatch with 200 hp. I would use the leftover money I had for a cobb stage 2 pack and a protune.
