Sorry, I was responding to your specific statement and I didn't realize that this was your question. The GT40 came in a multitude of color schemes if you bought one. The race color scheme was often different than the one that you could get if you bought a GT40 retail (Track cars were often baby blue with orange stripes, or Ford blue with white stripes. The cars that could be bought from the dealer came in a variety of colors, red/white. blue/white, and this actually includes a black and gold scheme, I believe). The joke is that you would NEVER...EVER....repaint such a rare, valuable and iconic car a color different then its original paint scheme. It would diminish its value.
EDIT: Also, if I had to guess, this car probably came out of the garage of a booster, probably Steven Tebo
