This is why I love my 80 series Land Cruiser (carb, not EFI), it's really simple that a lot of maintenance can be done with just wrenches. And the charm of having almost no electronics[1] on the car control is that if something is wrong, you will know it by the sounds it makes, and you will have a lot of times to fix it before it's completely toast. I have heard of horror stories about newer cars with electric ABS accumulator that stopped working on the high way, not with my FZJ80[2].
[1] The so called 'emission computer' unit on the car is a simple pulse counter/comparator that activates a VSV on the carb to reduce backfire while descending downhill with the foot off the throttle.
[2] My brake booster is leaking a little bit, but at least it won't suddenly gives up on me while I'm riding, still looking for a replacement.
I have an 80 as well (1997 LX450) and another positive aspect of owning it is that when maintenance items become due, a lot of them can be fun[1] and enjoyable to tackle, and very very rarely will you run into an issue that doesn't have threads and discussions talking about the best ways to fix it. One downside to that is that you normally have to do a little bit of legwork to filter out the noise caused by other owners also looking for how to solve that particular issue.

It does come with the territory though, and anyone owning an 80 (and probably a 100 series) at this point isn't doing it really to "save money" imo.
That being said, the recently outgoing 200 series LC didn't really do all that much better[1], and neither does the new 300 series.[2]
