We are seeing increasing numbers of used car fraud ads online where the "seller" emails you to use "Yahoo Payment Agents", "eBay Payment" agents, or "Google Checkout" or "US Amy Protection Services". None of these entities performs escrow or payment services for used cars. It's all fraud using logos and brands you trust in order to fool you. Use your head, they are only listing services. Any seller offering to pay shipping on a car is 100% certain to be fraud. It can cost $1000 to ship a car across country. What seller would really pay that for you?
