Dean,
No meatballs. No racing stripes. None of that, "Look at me I have a race car". BMW & MB currently make some really nice classy adult colors, ie. Anthracite, Black Pearl, Titanium and a beautiful dark Green metallic. Sponson/Rocker panel stripes only in Volkswagen Reflex Silver with some white pearl added. I have the "recipe" if you want it.
Just my .02
Cheers,
Scott
