GMC retail sales were up 23 percent year over year in July, closing at the highest sales volume since 2006. Total sales, up 14 percent, were the best since 2007. Sierra, Acadia and Terrain all posted July sales gains as the brand had its best seven-month start in six years. The all-new 2014 Sierra full-size pickups are leaving dealer lots almost as soon as they arrive. The average “days to turn” is 14 days, compared to the segment’s 76-day average. Combined with 2013 models, the new Sierra helped drive the pickup’s best July sales since 2007. Year-over-year Sierra retail sales were up 53 percent while total sales were up 49 percent. “The all-new 2014 Sierras are selling as soon as they come off the transporters, especially those with the SLT trim package,” said Tom Sheehan, owner of Sheehan Buick GMC in Lighthouse Point, Fla. “Our customers have told us they enjoy the luxury features that the Sierra SLT has to offer.” With all-new advertising hitting the airwaves, and the new double cab Sierras now shipping to dealers, the momentum continues for GMC’s best-selling model. Earlier this year, the 2013 J.D. Power and Associates U.S. Customer Service Index (CSI) Study, GMC ranked first among mass market automotive brands in customer satisfaction. The study examines satisfaction among vehicle owners who visit a service department for maintenance work during the first three years of new vehicle ownership. Acadia crossover SUV retail sales were the best ever for the month of July, with a total of 6,615 units delivered to customers. Year-over-year Acadia retail sales were up 1 percent, while total sales were up 2 percent. Terrain small SUV retail and total sales also were the best ever for July. Year-over-year Terrain retail sales were up 24 percent and total sales were up 3 percent. Both Acadia and Terrain are off to the best-ever start to a year. Source: media.gm
