The latest General Motors deal offered through the Costco Auto Program is turning consumers' heads, reaching record levels for the companies' partnership only two weeks into the offering.

The companies recently revealed more than 2,000 Costco members had bought a vehicle in the first two weeks of its GM Limited-Time Offer.

When compared to the previous two offers that came out of the GM/Costco partnership, this was a record high, the companies said.

What was so enticing to consumers?

This year, the promotion offers vehicles from all GM brands by adding Cadillac to the lineup,

The GM Limited-Time Offer also features GM Supplier and Friends Pricing, all publicly available manufacturer rebates and incentives for which they qualify, as well as a $500 Costco Cash Card when Costco members purchase or lease one of 14 qualifying GM models between Oct. 15 and Jan. 2.

The models are as follows:

•    Cadillac: ATS, Escalade, SRX and XTS
•    GMC: Acadia, Sierra, Yukon and Yukon XL
•    Chevrolet: Silverado, Suburban, Tahoe, Traverse and Volt
•    Buick: Enclave  

Commenting on the news, John Conlon, Costco services director, said, “We’ve partnered with GM to offer Costco members special pricing on their vehicles the past two winters and both offers did very well.

“During the 2012 winter GM promotion, more than 15,300 Costco members used the offer to purchase a vehicle. That’s nearly triple the amount of vehicles sold during the 2011 GM promotion. It’s clear, members see the value in the program and these limited-time offers,” he continued.

“It’s a great way to help members get into a new vehicle at a great price, raise awareness about our auto program and showcase various automotive brands.”

The Costco Auto Program — which has more than 3,000 participating dealerships around the country — also provides certified pre-owned vehicles, as well.
