^^^ The difference being that a 13k car after 2 years of abuse is worth zero, squeaks and rattles like a drawer of silver ware, and has parts falling off all over the place. You pay for more than just speed ya know.
I mean, you can make anything go fast. Look at the Neon. A total POS with bolted on power and to tell you the truth I wouldn't take one except to beat the living crap out of it and leave it smoldering. Which is why that thing is built anyway. Go fast disposable car.
