Haven't really seen anything that old in the local yards in a long time and what was there deserved to be.
Not quite as old, but sometime ago, I saw a '62 T-bird. Car was rough, but not rotted, and looked pretty complete. Probably could have been restored.
One that really upset me was a '79 Cordoba. I guess it had come from an Estate Auction/sale. I don't remember the exact mileage, but it was under 20K and the car looked it.
That's the bad thing about the PAP yards, there's no way to buy a complete car out of the yard.
