I read a story a few years ago about an eccentric old man that passed away. Rumors around town were he alot of classic cars.
The buyer got in contact with some of the family and made a deal to take a look.
The old man had several semi trailers back up door to door and removed the semi's tires. After finally getting the trailers separated when the doors opened, it was a gold mine. Several 50's corvettes, couple camaro's, custom ordered Nova and a few other classics. They were all very low mileage.
The crazy old man pulled all the motors and replaced them with different ones but he saved the originals. His thinking was if someone is going to steal them, they're not getting them original.
They were able to match all the #'s and put everything back.
There were also parts after parts after parts, all rare and all classic.
The old guy never had any kids, 2 of the nephews took a vette each and they sold the rest. I don't remember the total but it was astronomical.
