Maybe someone should contact this guy through the new ad and pretend to be interested, find out if he will meet to receive the payment... If so, take a local sheriff or cop along!
Also, has anyone reported this to Craigslist, to keep him from ripping off yet another buyer?
Bet this scammer isn't actually moving around himself, just using different regional or local online media around the country to pull his scam over and over. After all, why would anyone list a car that's in Kansas for sale in Nevada, and not in the Kansas City MO, Topeka or Wichita Craigslists? Sounds like he's trying to force a "long distance" purchase and avoid "buying locally" as is suggested, to avoid scams, right on the front page each Craigslist.
