Like many others, I too wonder what happened to the Cadillacs. If anyone can come up with the VIN numbers, perhaps they can be traced. Wouldn't it be cool to actually have at least one of them in working order? I'm sure lots of us folks would chip in to make it happen if they still exist and we could find them.
Oh well, just another pipe dream that's more fun to imagine than it is practical.
Thanks for posting this, Terry! It was a great find.
