Buy me a Mescherschmitt
$650,000 buys a ME109, or rather a Spanish built ME109alike powered by a Rolls Royce Merlin.
If you can’t afford that, $195,000 will buy a Bell TH-13T Sioux helicopter, which looks a little like the MASH evac helicopters but has been dressed up as a Vietnam era armed scout.
Or, finally, almost what I went looking for in the first place- a Bell TAH-1P Cobra helicopter, for $1,125,000. The guns have been decommissioned, but they can still simulate firing.
