Ouch. Had that happen to an Armada that the (ex) wife was driving. Insurance came out and took a look at it and recommended pointless dent repair. I flatly stated that was a fantasy, couldn't be done- I mean, this thing did t have a body panel that isn't get hammered.
Apparently, the guy that they sources for it made a living doing this I the Midwest during hail/tornado season. He would just travel around doing job after job on vehicles just like mine, and made a very good living. They ended up replacing the hood and roof because it was cheaper and easier (the roof on an Armada is a panel that is epoxied on; who knew?), but the rest was done by the guy with pointless dent repair. And you know what? I couldn't tell the difference- it looked like nothing had happened. Even the dents on the a-pillars came out. It was amazing, but this guy was something special- most of the guys that do this stuff are half-asses, the same kind of kids who go around fixing cracks and chips on your windshield (when I lived in Phoenix they used to hang around at gas stations and car washes and accost people there).
Long story short, there's hope for your 4Runner. The 80s are just a different animal altogether, and I love both (and luckily, have both!) but you really need to consider what you do with the 4Runner and what you would do with the 80. I'll tell you the obvious: 80s are much more expensive to work on, and you will have a much harder time finding spare parts at a salvage yard. And because of many small (and some big) changes that occurred through the 80s span, you won't necessarily be able to use parts from a different year. This isn't really as much as an issue with 4Runners.
What area are you in? I'd love to have a crack at the 4Runner if you don't want her
