My dad was thining of becoming a auto mechanic when he was in HS so he took a ton of classes on it and even leased a building and ran a shop for a while, but he ended up getting a diff job. Anyways, he makes me buy cars he knows about so when something goes wrong he fixes it himself. Once we had a car that he didnt know about so we took it in and they charged us way over so from now on he buys what he knows and if he doesnt know he has a friend who knows so we dont get stiffed. Those people will do things to your car to get you to come back. Ive had so many friends that has happened to with diff mechanics. I send them to my dad and hell fix it for free, just charge you for parts. He and my bro love to tinker with them so Im so glad. Itll be hell if I move out of OH and he cant fix my car anymore
