What the hell would you need 700hp for at under 21 years old anyways? Do you expect to drive around town with it?
LOL.
Anything more than 350 or so on a front wheel drive is pointless considerin you'll never even be able to fully utilize that much on the street.
And if you think you'll get an 06 type s with enough upgrades to make 700hp with $15,500 you better get your head straight. Just buy an eg hatch and build that if you want a fast car
