I don't believe this Imperial has been shown here before. YM43K9C236199 is currently for sale as a restoration project at a renowned Mopar shop in Germany:
The current paint color isn't described with a color code in the sales text, only as a pale yellow.
However, traces of the Surf Green Metallic are still visible, for example, in the engine compartment.
Many more photos can be seen at the link.
Kinda silly that they're offering it as a "roller" but yet they have the original engine in overhaul and will sell it with the car as an option... who WOULDN'T want the original engine with the car? Maybe their gas costs so much they'd drop-in a 1.5L four or something for you?
