GM sales dive 19%

General Motors Corp. sales dove 19 percent in July to 320,000 cars and trucks, according to sales data announced today.

Sales were down across each of GM's eight brands, including a 22 percent drop at Chevrolet, GM's top-selling nameplate. Truck sales were down 16 percent and cars sales fell 24 percent.

One bright spot: GM managed a 15 percent increase in retail sales to individual customers. The automaker has worked to increase retail sales while pairing back less profitable sales to rental fleets. Year to date, GM sales are down 9 percent.
