Costco’s car-buying program usually comes with some pretty sweet deals, and now it’s adding a limited-time promotion for the Ineos Grenadier. The offer combines Costco’s usual prearranged pricing with some extra incentives aimed at Executive Members.
Executive Members can get $2,000 off a new Ineos Grenadier, plus another $1,000 toward accessories through the Costco Auto Program. The offer runs from October 1, 2026, through January 4, 2027, and applies to both the Station Wagon and Quartermaster body styles.
How The Costco Auto Program Works
The Costco Auto Program connects members with a network of Approved Dealers that agree to offer prearranged pricing, taking some of the usual back-and-forth out of the car-buying process.
Members choose an eligible vehicle, register online for a savings certificate or member code, and then take that information to a participating dealer or apply it during checkout, depending on the offer. From there, a trained dealer contact handles the rest of the transaction.
For the Grenadier promotion, eligible Executive Members need to register at CostcoAuto.com/Ineos and receive a promotion certificate before visiting an Ineos dealership.
What’s Included With The Ineos Grenadier Deal?
The Grenadier promotion gives Executive Members a $2,000 incentive on any new 2026 or 2027 Ineos Grenadier, along with a $1,000 accessories credit that can be used to outfit the truck.
Buyers can choose between two very different body styles. The Station Wagon is a five-seat SUV aimed at families and outdoor enthusiasts who want serious off-road capability without giving up passenger space. The Quartermaster is a dual-cab pickup that sacrifices some cabin space for a larger cargo bed.
Buyers need to take delivery of an eligible Grenadier by January 4, 2027, to receive the savings. If you miss that deadline, the certificate doesn’t carry over to a later purchase.
