It's someone's attempt at creating their own version of an RS. Factory Sample means he paid extra to have Porsche paint it that color. Simple enough to add the graphics. He calls it a GT3 but doesn't make any claims about extra HP. Think it's a collection of special order options, not a factory special. You could get a 2008 Cayman in this paint scheme.
Wonder how well the black and beige interior coordinates with the green?
