Car repairs are easy when you know what you're doing, but to many people cars are a black box. It's easy for you or I to walk up to any car and change the oil, but that's because we have experience & the confidence that comes with it. There's also a lot of mistakes you can make even just in changing oil. I won't make them, but that's because I've already learned the hard way. John Doe has yet to put all the mistakes behind him.
