If you've been shopping for a Grenadier Station Wagon or Quartermaster, Costco's Executive membership offers a meaningful incentive.Following Land Rover's discontinuation of the OG Defender, Ineos filled the void with its Grenadier design. This means that the SUV has become everything from open-topped safari rigs to military pickups.Welcome to Shop Smarter: A series dedicated to highlighting not just what's on sale, but why it's worth owning.

Along with the boxy look, it brings a BMW B58 powertrain, and, in keeping with its off-road aspirations, it pairs rugged ladder-frame construction, a two-speed transfer case and locking front, centre and rear diffs, not to mention solid beam axles.However, in an effort to make the price tag a bit more palatable, Costco's Auto Program is now offering Executive Members a $2,000 incentive plus a $1,000 Ineos accessories credit (amounting to $3,000 in total value).The deal runs October 1, 2026 through January 4, 2027, and it applies to both the Station Wagon and the Quartermaster. For anyone already eyeing the brand's offerings, it presents a straightforward way to lower the entry cost while stocking up on branded gear.While Costco notes that interested buyers are required to have held an active Costco membership by September 30, 2026, the stipulation allows for upgrades. As such, Gold Star and Business Members can upgrade before registering.It's worth noting that the deal can be layered on top of other promotions. Ineos is currently offering as much as $3,000 in customer cash through its specials, and any local dealer discounts apply, too.The Grenadier can be outfitted with all kinds of gear, making the Ineos credit a worthwhile proposition. - Credit: IneosThe incentive applies to both Station Wagon and Quartermaster. - Credit: IneosThe money saved can be used for other expenses on expeditions. - Credit: IneosIneos Grenadier Station Wagon Learn More Ineos Grenadier Quartermaster Learn More About the Author: Gray is an associate editor at Gear Patrol, covering cars, motorcycles and anything else with wheels.
