The car in the picture that you posted as your inspiration was owned by a guy named Scott Sloan. I know that because it is one of my favorite examples. I used it as my inspiration when I built my car. Porsche 5710 Stone Grey exterior with dark brown leather interior. Also Joe @Joe Fortino has a beautiful stone grey car. If I were doing it all over, I may choose the red interior like Joe's car.
Here is my car. Just a home built CMC. The color looks very different in different light!
