He said was 02?

Ok so this kid near me is selling this...

First thing - Car has been 5 feet off the ground at 120mph...

Car was built, then bought, He paid $13500

SWAPPED KA20AG $2800 Has paper work - 79k mile motor, 6speed, Only bar minimal things to boost the motor
Dyno'd at 395hp on 9psi, and 425hp on 11psi
Precision tune turbo - I've never heard of it
Upgraded injectors
Coilovers
Carbon fiber hood
White on black
Black leather interior
Chassis has 80k miles
FMIC
3'' Downpipe - Nothing is heat wrapped

Oil sits in the turbo and causes it to blow white smoke but only sometimes

FL car, I didn't see any rust

The car supposedly will do 180mph

Basically i'll be paying him anywhere between 5000-8000, if he sells what we're trading right

What's the car worth? can i get more for it?
