The Costco Auto Program has added the Cadillac SRX to the eligible models available during its promotion with General Motors.

The addition was prompted by a large number of requests by Costco members for existing Cadillac models currently offered through the program.

Costco members who purchase a 2014 or 2015 Cadillac SRX from Dec. 10, 2014 to Jan. 2, 2015 are eligible for the special offer, so that the company can meet the growing demand for luxury models.

 The Costco Auto Program launched the Costco GM Holiday Sales Event, Oct. 1, 2014, offering 17 select 2014 and 2015 Chevrolet, Cadillac, Buick and GMC vehicles at GM Supplier Pricing and additional benefits.

All qualifying Costco members will get manufacturer rebates and incentives, and a $600 Costco Cash Card for Executive Members or a $400 Costco Cash Card for Gold Star and Business Members for completing certain eligibility requirements.

"The models offered at the launch of the promotion were already some of the most-requested models by Costco members, said John Conlon, Costco Services director, in a press statement. "Adding the Cadillac SRX is a great opportunity to show a value to even more of our members."

Costco says that more than 45,000 members have registered so far for the event, which is 43 percent higher than the same promotional period in 2013.

Data collected by the Costco Auto Program shows that the Chevrolet Silverado is still the most-requested vehicle. GMC Sierra is a close second, followed by GMC Acadia, according to the company.

The Costco Auto Program has provided Costco members a great service for close to 25 years now. It offers a hassle-free buying opportunity to members the entire year, through its network of nearly 3,000 selected dealerships nationwide. The company also trains and certifies Authorized Dealer Contacts at these dealerships to make sure customers are getting the best service possible.

Members can also access online tools to look into and compare vehicles, find participating dealers, and make a purchase at a prearranged price.
