It happens all the time, especially for campervans.
Posting an ad. for a motor vehicle on eBay is as easy as copying someone else's photos, and pretend to be selling it. In a TV programme about organised crime last year, a senior police officer reported that one criminal gang in London alone had registered "multiple hundreds" of fake accounts on eBay to place fraudulent listings for motor vehicles.
There is no buyer protection for motor vehicles sold here, and untold numbers of buyers have paid sellers unseen for vehicles that turned out not to exist - in one morning alone we heard of three buyers who each paid over £6,000 for cars that paid for non-existent cars.
There are almost certainly hundreds, and possibly thousands of fake ads here for motor vehicles at any time. If you can find your campervan there is a link in every listing to report it (on the right, level with the postage and payments tab).
