Description
This top of the line Sierra Denali Ultimate is finished in stunning Onyx Black with the exclusive Alpine Umber interior, delivering a perfect balance of bold presence and refined luxury. This ex lease diesel pusher has had only two owners and shows exceptionally well, with less than 16,000 kilometres on the engine, making it a rare opportunity to own a flagship truck in outstanding condition.

Powered by the proven Duramax diesel, this Denali Ultimate offers effortless torque, impressive efficiency, and confident towing capability, all wrapped in a remarkably smooth and quiet driving experience. Inside, the cabin is loaded with premium materials, advanced technology, and comfort features that elevate every drive, whether its a daily commute or a long road trip.

With over $13,000 off MSRP, this truck represents tremendous value in the luxury pickup segment. It has passed the Dueck Certified Inspection and is fully serviced, inspected, and ready for new adventures with total peace of mind.

Independent automotive reviews consistently rank the Sierra Denali Ultimate among the very best luxury trucks on the road. MotorTrend has described it as the Maybach of pickup trucks, praising its ultra premium interior and ride quality. CarBuzz highlights the Duramax diesel as the ideal match for the Denali Ultimate, noting its strong torque delivery and impressive fuel economy. Edmunds applauds the Sierra for its upscale cabin, advanced driver assist technology, and the versatility of its diesel powertrain, making it one of the most well rounded luxury pickups available today.
