NEW ORLEANS (AP) — At this year’s version of the National Automobile Dealers Association convention, survival has passed maximizing profits as the focus of the annual event. So as thousands of dealers from across the U.S. gathered Saturday in New Orleans, they were greeted by workshops entitled “Selling up in a down economy: Taking the bull by the horns” and “Tough times, tougher dealers: Saving your dealership’s assets.” Sales last year were 13.2 million, down 18 percent from 2007.
