15 year old Camaro or Mustang, salvage title bimmer, G35, pre-smog american 4 door with a decent v8 (most 2 doors are out of your price range), high mileage WRX, old compact shitbox like a Maverick or a Vega with a built small block. There are lots of ways to go fast for seven grand.
Fast and Cheap
You say want the the fastest thing for less than 7 grand.
And then you say it can't be a bike, is akin to saying I want run as fast as I possibly can, but only using crutches.
i also asked for a car, kind of important
If you find something reasonably quick under 7grand its going to be at one or more the following.
Unreliable
Needs a shit load to get it running.
Will be slower than anything made in the last five years.
Still won't hold a candle to a literbike.
Still a car though, not a crotchrocket
Is street legal required? If not, I bet a kart could make a pretty strong showing.
Gsxr1000
the point is to drive it on the road, so yes
Liter bike you pussy. Bikes don't need to be smogged so you can do whatever mods you want to it. Not that you need to modify them.
this user is right. think about the age old dogma:
>fast
>reliable
>cheap
You can only pick two.
