Loc: Valley Ford CA!!!!
Oh sure, its a Nudiemobile, and in a museum. Just not the RR Nudiemobile and not in the RR Museum, which is the key here. I don't think its a Caddy either. Nudie favored 64 Pontiacs (did only one Caddy, I think), and I am pretty sure this is one of the Pontiacs, just not a Bonny. Anyway, its not the car, but the location and what goes on there, that is the obscura here.
Wherever you go, there you are. SPOTMe!
