Spaw,As good as the Slant Six was my vote for the workhouse engine of all time would be the 1600 VW. How many bugs did you see go a couple of hundred thousand miles before the rust ate the body away. The only thing that could be done then was to cut what was left of the body off and make a dune buggy. These usually went until the owner lost interest and abandoned them.
Unfortunately the worst heater/defroster system I've ever seen also goes to the VW bug. I always used to have an ice scraper close at hand to scrape the ice off the inside of the windshield.
Murray, thanks for enlightening us. I, for one, wasn't aware of that.
