I'm sure some of our guys here in the WW2 aircraft business could tell us what the costs of ownership is of one of these birds. I'd guess that it's as much, perhaps even more over the long term than the actual sale price.
It would be interesting information I'm sure, considering what I know a 172 costs to keep up every year what with annuals, fuel, maintenance, storage, and god only knows what else.....I'd love to see the yearly costs of some of these great warbirds.
