Drove one from 1988 to 1993. It was a 1981 that was the last year with the air cooled engine. I was amazed at how easy it was to work on it. But underpowered? Yes. That is part of the charm. I enjoyed it, but wouldn't want another one. I'm back into self propelled sports. Bike touring, canoe tripping, backpacking. No need for the status of being a VW Van owner.
I never heard a good report on the 1982 + vans with the liquid cooled engines.
