That's the topic of this article by consumer journalist and advocate Christopher Elliot. The article caught my eye for two reasons. First, it's fairly in-depth consumer journalism that used to be commonplace. The writer investigates and reports on a possible consumer rip-off, suggesting what might be done about it and, in the meantime, warning consumers about how to avoid the problem. Second, the topic struck me as worth knowing about. Here's one possible rip-off, according to Elliot's article. It seems there is some evidence that major car rental companies rent cars that already have some body damage, perhaps damage that can only be detected on close inspection and the car rental company apparently didn't notice when it occurred. The companies don't disclose the damage at the time of the rental. Then, the consumer returns the car in the same condition as when it was rented, but, lo and behold, the consumer is charged for the damage. The British Columbia attorney general is investigating. Elliot would like to see the FTC investigate as well.
