The black Turbo is actually Black Granite Metallic and Onyx Pearl. The top color is black with Red metal flake mixed in, the bottom is sort of a light graphite grey. I love the combo.
Originally, the body cladding would always be silverstone metallic. The idea being that when the cladding was damaged, it could be replaced without having to paint-match. but too many people rightfully griped about it and now we have more choices. I still wish that WR Blue Pearl monotone would have been offered.
