Recommendation: Do your own work on your own vehicles. Research on the net, find the problems, watch a few YouTube videos and learn. You'll have to buy your own tools and you'll always have the experience to do it again. Those tools can make you a few bucks on side jobs, like working on other's vehicles. For more complicated jobs, video yourself taking things apart, so you know how to put them back together. Treat the camera like a child and show it what you're doing as you go.
