This may not be focus on speed as so much that color says a lot about the driver. I did look at a yellow 2000 Boxster but it screams look at me. Silver for me is too blah. Black is smart(but u will see me in the carwash a lot). Greens, reds, blues are good too.Whatever turns your crank. It does not matter the color here because everybody looks at a Porsche irrespective of color. Every Porsche color is right though.
