Boring paint- ideas please

If you are looking for a visual change on a shoestring budget, I'd like to see the rear panel blacked (matte, semi-gloss, gloss ... I'm not sure) out as well as the grille (in order to balance out the front and rear). The two light colors on the car wash it out a little and some dark, bold color might break it up.

Also, I would like to see the pinstripe separating the top and bottom colors much bolder and wider (perhaps wider starting in the rear and tapering towards the front). On the front fenders, you could slightly break the stripe up and include a more subtle 360 engine designation (vs big ol' numbers on the rear quarters). Of course, the stripe would continue after the 360 call out (while tapering) towards the front. You might want to consider giving the 360 a slightly forward look (ie. slant) towards the front of the car. Just some thoughts working within your parameters.
