GM sales up in July

July sales for Chevrolet, Buick, GMC and Cadillac increased by a combined 25 percent to 199,432 units. Buick and Cadillac brands each sold more than twice as many vehicles in July, compared with the same month a year ago. July marks the 10th straight month in which total and retail sales for GM's brands increased year-over-year, demonstrating the continued strengthening of each brand in the marketplace as GM continues to rebuild momentum a year after its launch as a new company.
