Stop in for a cup of coffee

you're telling me that if you had a yard full of rare cars that were too far gone to restore, including race cars, that you'd just part them out?

Yep. Although they wouldn't have been out in the weather like that to start with.
If you have the resources to obtain them, do something with them.
Otherwise what's the point.

As an example. If you could get your hands on historic documents, would you carefully preserve them. Or just toss them in a box.
