Good advice. I'm very fortunate to have a good shop that I've been using for many years. At this point, I just drop off a car and tell him the "make it right." He understands what that means and does not call me up to get authorization for every $100 nit that he finds. If he asks me to make a decision on a repair, I normally ask, "what would you do if it was your car?" and follow his advice. He explains exactly what he did and why he did it, I don't nitpick the bill, and he is more than fair with his charges. I tell him if I need it done fast, otherwise I make it clear that it's not a rush. When I do need something in a hurry, it gets done fast. I know all his guys, and they know me and my family. If my wife has a problem while I'm out of town, I call him up and ask him to "take care of it." He's not cheap, but he does excellent work and I trust him.
