I never see used Hummers on the road?

After my time. We had weapons carriers and deuce-and-a-halfs.

I see a few EV versions on the road. (I know OP was asking about used ones from the olden days)

Yes, pretty sure. I still see things like say a Focus or a Camry from the 00s, but they don’t seem as common as cars from the 60s were in the 80s. Now, I live in Texas, where cars don’t usually rust as rapidly as they do in other areas. So that could be why vehicles from the 60s were long lived here.

I think’s that’s the key reason: people who can afford the gas can also afford a newer car.

A good vehicle for specialized uses. There were also a few surplus Military ones.

A piece of shit.

Just Saturns out here. Damn those were great cars.

Consumer Reports year after year puts those on the bottom of their reliability ratings, along with Jeeps.
