Hi and welcome!:welcome: Your S2000 looks very nice, are you going to use the hardtop (roof) or not? In the mock-up I think the height is a bit too low but the wheel look great! Any other special plans for it or just going for a "stock"-look? As for a nice paint I think just about anything will look good, but if I were you I´d do following. Put carbon fibre decal on the hood and paint a "smoke" coat over it, chrome or gunmetal on the wheels and paint the body black with a blue "candy"-effect.
Good luck and keep up the progress!
