The hard part(especially for large vehicles) is to survive that era past when it is valued as a working vehicle and before it is valued as a historical vehicle, At that point is is just junk. Large expensive junk.

I was recently reading about the original great Chicago wheel(The Ferris wheel). it lasted about 10 years, nobody wanted it. The contract said the fair land had to be restored to original form. So they just blew it up, nothing left, did not even try to save a car. The other disappointing part was that Ferris was a bit secretive and no technical drawings for it are known to exist. I really wanted to know how it was powered, more that the blurb you get in the articles. Best I found from the pictures is there are cast wide spaced(not gear spaced) drive slots riveted to the rim and vague mentions of a chain. Some sort of wide spaced bicycle type chain in partial engagement against the rim?

See also: The USS Enterprise(CV-6) if any ship deserved to be a museum ship that one did, but they were not able to muster the enthusiasm needed at the time she was broken up.

The reason it well preserved is the brackish water in Baltic Sea where the shipworm doesn't thrive.
