does this exist?

Is there a website that allows you to design a car, like with different color schemes? Be it a 350Z, a Ferrari, or even a Lancer. Just a way to try it out.

photoshop, if you can't do it i'll do it for you just tell me what can, and what color

For several years now, R/C guys have been taking the promo pics of the car bodies and whiting them out in Photoshop, leaving just the detail lines. Then they take that template and play around with color schemes to get an idea of how they want to paint it.

It should work just fine with real cars or models.
