KNBC Channel 4 here in Los Angeles has a reporter named Joel Grover who does something I like. Every so often, they send him out with hidden cameras to take a car to various mechanics and document the rip-offs. In his latest expedition, he went to ten outlets of the EZ Lube chain and six of them prescribed unnecessary repairs and/or charged him for repairs they didn't perform. What's interesting about this is that is the second time Glover has had this experience at EZ Lube outlets. In fact, at one, he encountered a manager who was one of the guys who swindled him the last time he did this kind of survey. Here's a link to a video report.
