curbstone
 n.— «By the late 1970s and early 1980s, prosecutors said, Schecter had learned how to “curbstone.” That was the street term for buying cars at auctions and from wholesalers, rolling back the odometers and then placing ads in newspapers, pretending to be the original owner.» —“Time on the run, then time to pay” by Stephanie Hanes Baltimore Sun (Md.) Nov. 20, 2004.
