There were parody used-car dealer ads long before the legendary "Big Bill Hell's" Here's Kris Trexler on this one from the 1960s:
This "gag" commercial never aired of course. The pitchman was well known in the San Francisco Bay Area in the 1960s-70s. While taping commercials for the dealership in 1968, the pitchman made this gag take to poke fun at his boss. Ralph Williams owned many California car dealerships and had quite a notorious reputation.
