You'd be losing money in the long run no matter what. Bodykits/rims/engine swaps... those all add to decreasing the value of a car. stuff like that makes the car appear to have been raced... and who the hell wants a car that was beat on? $6.5k should be more than enough for a CRX though... you can get an exceptionally nice CRX for (at the very most) $3k. But then.. if you're looking for one with a b16/b18 already in it, they'll probably be asking more for it, because the majority of the population thinks that because they put more money in it it's worth more. either way, $6.5k will get you more than a CRX... hell, I'd say look around for one with a zc/b16/b18/jdm/gsr/whatever motor already in it.. a lot of them being sold have a nice interior and exterior. So you may be paying more like 5K.. but you bougt a nice enough car.
