True, many save-able cars have been lost over the years to the "I'm going to fix it up someday" crowd.
Let's face it--the old-car hobby attracts more than its fair share of hoarder-type personalities.
Car guys know the worst thing you can do is have these things sit--especially out in the elements. But some guys would rather leave it sit and rot that sell it. To each his own.

It's their car to do with as they please--at least until they pass away. Eventually we all gotta go sometime, and we will either leave our heirs with something useful and valuable, or with a rotting hulk they need to have hauled off to the junkyard. Either way you can't take it with you.
