Guy replies to my autotrader ad. Says he has a "client" who is willing to pay me "x" amount for my truck. The trick is he wants to send me a cashier's check for like $8,000 plus over what the "client" wants to pay for the truck. I'm then supposed to send the balance minus my amount back to the "client" so he can offset his shipping charges. Yeah right, sure pal... ... I smell a rat. Any of you know how this shenanigan works?
