I didn't see a Valencia. I only knew of a source silver (high 160? - low $170?) and a 130r (176K) when a forum member listed them here on this forum. When I inquired about them, the source silver was gone a fews days before. I would have definitely picked up the silver from you simply for the price it was selling for (as would others including it's buyer.
) Perhaps the Valencia was sold before then or came in afterwards.
Nevertheless, a $6k up-charge on Valencia is perhaps enough to sway buyers to pick up even a source silver over it, all else equal. I guess the color in itself is not super-car exclusive enough to command that premium. (An orange, yellow, or a Green beast from hell AMG green could hopefully prove so.). The more interesting question would be is if both colors (Valencia Red and silver) cost the same and you had two cars with the only difference being color, would the Valencia still sell second to the source silver? I would lean toward saying the Valencia would sell first...
