For just a few dollars more you could theoretically buy one of them. As of October last year they had three on offer for at least
$2,000,000 each. That's just over a million pounds, which is tantalisingly graspable if all you want from life is to own a detailed and flyable Me262 replica.
I can't imagine how you could recoup the cost from exhibiting it etc, unless you had a special device that could take an Me262 apart and spit out duplicates. Perhaps the Chinese will work out a way to mass-produce them.
In the future this kind of project will be more practical. Ford recently reproduced the old GT40 race car, and very impressive it was. I'm sure that Jaguar would make a mint if they brought the E-Type back into production, with updated engines, electronics and so forth. There are lots of kit car manufacturers, but they don't have Ford's marketing muscle. Perhaps a hundred years from now, when everybody has a pilot's licence and people commonly commute to work with jet-packs, there will be a market for flyable replicas of WW2 aircraft. Although by that time WW2 will be as distant as the Napoleonic wars.
