My wife got one of these ads from a car dealership. It was made to look like an Outlook email printout from a sales rep at another dealership addressed to the guy who had sold her car to her. The email stated that the dealership had an interested buyer for that particular model year (about 5 years old) and that hers was the only one in the area. They said that if she came in, they would give her a free oil change and offer her above market rates for a trade in. The printout had what looked like a hand-written post-it stuck to it asking her to get ahold of the sales rep in question. I was suspicious but she followed up and found that the sales rep who had supposedly sent the email was not even a real person. It was a pretty advanced scheme to try to cover up the fact that it was just a way to get her into the shop, inspect her car, and find all sorts of problems with it and pressure her into trading it in. Probably the scummiest thing I've seen in a long time.
