I agree he should restore it. But a legitimate barn find is way cool. Whether it's a car, truck, tractor or some other valuable or cool antique. I've spent many hours trolling old buildings (with permission) and seen some cool stuff. Never a wing car.
To say that they were left to rot isn't accurate. Storing something and forgetting about is way better than leaving it outside to rot.
You recognize that superbird in pieces in the wing car forum. The one that you drove by many times as well as all of the other cars that the man was letting rot outdoors.
Just imagine if they only had a roof over them for all those years. They would be in good shape and Somebody would be restoring them right now instead of scrapping them.
I have a barn full of Old vehicles that I found in other barns. Maybe I will get to them, maybe not. But they are certainly not rotting away. They are in suspended animation.
