It was one of the 959SC restomods, so not factory. IIRC it used to be silver. The Garnet one is probably my favorite 959 that was painted that way from new.(Please excuse that I'm bumping a 5 year old post.)
If I knew that a green 959 existed, then I would have seriously rearranged my life goals and bought more lottery tickets when I was 14 and moved to Europe...wait, that was my life goal back then.
