Little Broncos rust in ways that make Vega's jealous.
However, if you can find one that is dry (or has had a fiberglass tub replacement), the rest isn't bad. Bronco geeks put a lot of weight on 'uncut' bodies; the rear wheel openings were rather small, so many of them have been hacked to fit larger tires. During the 1 week I shopped for one 30 years ago, it seemed that the drivetrains were typically stick = six cylinder and automatic = V8. I imagine you could mix that up, but almost every one I looked at was spec'd one of these two ways. The six is frugal and reliable but not particularly powerful.
The Scout is an alternative but sends you into a whole different world of parts...IH's were sort of like AMC's and used parts from different manufacturers (like ignitions). The parent company has absolutely nothing to do with them anymore so the aftermarket and clubs are your only source, and they are limited. They are also rust bombs, about equal with the Bronco. Still, the Scout does have a lot going for it, but I find them a bit bland and minimalist compared to the Bronco.
