If I were swimming in extra cash, I could see getting one of those electric crate motors, to put it into a late 50s-60s land yacht. Something huge and weird looking, like an Imperial or pre-61 Lincoln. It's hard to justify driving something that gets single- digit miles per gallon as the planet warms and the seas rise.
Then again, if you equip them with a powerful electric motor, you still have crappy drum brakes, so you should upgrade those, too.
