Miss Ellie the druggist drove the Comet wagon in the show. Perhaps the CS was Andy's personal car? Don't recall seeing it in any of the episodes. Otis Campbell drove the Ford ragtop.
When I was a kid, living in Georgia, my dad bought a 60 Country Squire that had a Merc 390 in it. It had been a local moon runner's car. A local gas station tested it to see how much horsepower it had, and told dad it was up to 405 on the bhp.
