So,
You've done the L28, The triple Dellortos, The Triple Mikuni, The 2+2, The 2 Seater, The Flares and Spoilers, The racing stripes, The silver, The White, The retro ....... budddy!!!! Don't think outside the box, Re-invent it. Showcase your talents with a car that will become part of your sole.
I'm going to offer a suggestion.
RB30 Turbo 2+2 in in Grand Prix Brown Metallic with standard Alloy wheels resized to 15 X 7.
And then .... don't sell it
