My elderly mother brought her car in for service, and they sold her many parts and services (at an astronomical upcharge) that she didn't need using scare tactics. (I'd verified most of these parts beforehand) When I immediately went back, they said they couldn't give me the parts they had taken out, and laughed. I asked if they thought those charges were reasonable and they said no, but my mother should have known to check. Exact words: "If she can drive, she should be able to understand what services are" I would never trust them again. Awful preying on customers like that.
