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.
Starter replacement on my strait-six LX450 took ~1 hr. Pull the wheel and you're practically looking at the unit. OTOH the Birfield Joints are kind of like prehistoric CV joints and have to be rebuilt in-situ. I love mine, 400k+ miles, still going strong and slurping fuel at 14 mpg.
mine had a leaky rear main seal. That was not a fun job. Fortunatly, my brother is an experienced auto mechanic (with ~$50k of SnapOn tools). So we were able to get it done, but there is no way I could have done it myself. The vehicle had 300k on the odometer and ran perfectly when I sold it last year for more than I paid. The reason I sold it was that the plastics had got brittle from the UV in the new mexico sun, so much of the interiod was falling apart.
