I've had people try and do this but it's not nefarious, just bad business. A guy explained it to me when he was trying to convince me to take the deal. He had three credit cards and if he maxed them out on Paypal he could buy my 356, and then hope to re-sell it within 30 days before he has to pay interest on the cards.
I declined and would never take more than a deposit through paypal. If he gets the car and doesn't like something he could tie up a lot of money. Not to mention the 3% adds up.
