The 50's and 60's cars are easy to find, the 70's get a little tougher because they're not as collectible and they rusted away at the drop of a hat. I say 50's and 60's are easy to find, that doesn't mean it would be easy to talk the collector into loaning it to a studio.
It would take a pile of money and bulletproof insurance. I saw several of those Hudsons last summer, I'm fond of them because a '51 Hudson gave me my first ride over 100 mph.
