It looks to be something like a Centurion Conversion on a F150 frame, I passed this up near Huntsville Tennessee in a used car lot.

 

Interesting.

 

I think that is a Centurion. Or a knock off. I've seen one or two in person. Very rare. Always thought they were cool!

 

I had an 87 Centurion F250 but like you I do believe it is a C150. I know the thing is a rust bucket and it has been there for quite a while with the window down.

 

I know Centurion made some C150 4-door Broncos, and the rusty roof makes me think it IS a Centurion. The fender is clearly a replacement, which would explain the lack of a C150 badge. Next time you pass by it, see if the other side has the Centurion badge.

It has had the front end replaced, both fenders say F150 XL but the tailgate does say Centurion Steve.

 

That car lot looks a little like the one from the movie "used cars". I especially like the stack of used tires. All three of them. Lol.

 

I’ve never seen a ‘92 Expedition before.

 

Looks like the 4th is in the grass Ken

 

An Expedition isn't half-convertible, and doesn't have a tailgate with power window.
