Found for sale on eBay is this flamboyantly unique Audi S5 Coupe featuring a killer color combination that makes it stand out like a lime in a bowl of lemons. And this ain't no vinyl wrap; the "Porsche Lime Green" exterior finish was a special factory order that cost the owner $2,500. Open the door and you'll see why most manufacturers don't allow customers to combine certain exterior shades with certain interior colors even if they are available.
