Good info Mark.
Whatever color mine is, it was definitely done at the factory. There is no indication of any other color of paint under the hood, inside the entire engine bay, in the door jambs, etc. Also the leather separators they put between the body panels are still in good condition and have zero paint on them. It would have been impossible for them to be properly masked as complete disassembly of the body would have been required. Not likely
Getting the proper paint is no big deal. I will get our local paint store to computer match for me. It would probably match better anyway.
I'm thinking the car may have been special ordered from the factory although the window sticker mentions nothing.
