Willie, I can identify with your comic strip. I grew up around the automotive repair business. My Dad was a self-taught mechanic who opened a wrecking yard/garage when he returned from WW2. He was the service mgr. at our local Ford dealer. We had a parts store, a body shop, a radiator shop, and a battery/electric shop. In 70 he was elected County Sheriff and served for 8 years before he died of Cancer.
