He is the challenge:
I want to buy one car to last me until fossil fuel cars are no longer a thing.
I need a car that I can rebuild again and again till it has gone a million miles or more.
What are the best cars for this goal?

anything carbureted

Mini. You can buy literally every panel reproduction

1975 Chevy longbed

Some kind of Chevy truck or Panther Ford.

>Panther Ford
what is that

It's going to be a '65-'85 Chevy, Ford, or Dodge pickup. All of them are still plentiful, built like tanks, and have significant parts support even today.

Next would be a GM or Ford full size from '65-85 or so but they're thinner on the ground and parts support is nowhere near what the trucks have.

Mercedes-Benz W123 diesel. 240D if you can find one. 1983 and earlier.

Cheap plentiful parts, easy to work on, interior wears like iron, runs on nearly anything you put in the tank, no electronics, and is actually quite nice to drive.

Will go hundreds and hundreds of thousands of miles with basic maintenance and care.

Any F series with the 4.9 inline 6. Literally will go forever

A panther body Ford is the chassis the crown vic uses, and all its derivatives
