#1, Gomer was only a pump jockey…he was never portrayed as a mechanic. Yes he wore a uniform, but there was no self serve then, and they cleaned windshields and checked under the hood. He may have fixed Opie’s bike tire once or twice, though.
He did end up as a fine Marine: http://www.youtube.com/watch?v=r5KeGccP9Jk
