SAN DIEGO — General Motors has once again partnered with the Costco Auto Program on a Holiday Sales Event, which kicked off on Oct. 1 for Costco members. This year’s event will feature models from Chevrolet, Buick, GMC, Cadillac, including models not offered last year like the Chevrolet Colorado, Buick Cascada, Cadillac XT5 and GMC Canyon.

Costco members who register for the Holiday Sales Event at Costco.com/GM, then purchase and take delivery of a qualifying vehicle between Oct. 1 and Jan. 3, 2017, will receive GM supplier pricing, as well as most currently available GM incentives. In addition, Executive Members will receive a $700 Costco Card and Gold Star, and Business Members will receive a $300 Costco Cash Card for purchasing a qualifying model and completing all eligibility requirements.

“General Motors is excited to partner with Costco Auto Program to bring this valuable offer to Costco members,” said Jim Cain, GM spokesperson. “Seeing the continued success of the Holiday Sales Event with each year, GM is pleased to offer the largest selection of vehicles to date for Costco members that will make the event just as popular, if not more so, than last year’s event.”

Last year, nearly 58,000 vehicles were sold during the three-month promotion, a 34% increase from the prior year. Additionally, more than half of the people who purchased vehicles during the event said they switched to a General Motors brand because of Costco’s promotion, according to Costco officials.

For the full year, the warehouse retailer’s lead-generation program resulted in 465,000 units sold through its 3,000 dealer partners — a 16.8% increase from 2013. The No. 1 U.S. auto retailer, AutoNation, sold 533,000 vehicles in 2014.

The Costco Auto Program promises a streamlined buying experience for Costco members through “specially selected dealerships nationwide.” Contacts at participating dealerships are trained and certified to deliver “superior customer service.” The program also provides online tools to research, compare vehicles, and locate a participating dealer to make a purchase at prearrange price. Costco also offers member advocates to guide and support Costco members throughout the purchase process.
