Here, resting quietly on the lot, we find a magnificent specimen in Summit White, a 2024 GMC Sierra 3500HD Denali Ultimate with 33,774 miles on the clock. Under that long hood lives a Duramax 6.6L V8 Turbodiesel, a powerplant of almost geological patience, paired to a 10-speed automatic transmission and full 4WD. This is a truck built to move things that would make lesser vehicles weep quietly into their oil pans. The Snow Plow Prep and Camper Package, integrated trailer brake controller, ProGrade Trailering System, and dual 220-amp alternators suggest this animal did not evolve to sit still.
Step inside and the creature reveals its softer nature. Full grain leather in Alpine Umber wraps the cabin in a warmth that feels almost apologetic given the brute outside. Both front seats offer 16-way power adjustment with lumbar support, ventilation, and heat, and the second row passengers have heated seats of their own. A 13.4-inch GMC Infotainment display commands the center of the dash, while a 15-inch multicolor head-up display keeps the driver's eyes forward where nature intended them to be. The Bose 12-speaker audio system, wireless charging, Apple CarPlay, Android Auto, and SiriusXM with 360L round out a cabin that takes its creature comforts seriously. A console-mounted safe and rear underseat storage speak to a species that values both luxury and practicality in roughly equal measure.
Outside, the Signature Denali Grille in Vader Chrome gives this truck a presence that other vehicles in the parking lot tend to give space to. The HD Surround Vision, Hitch Guidance with Hitch View, bed view camera, trailer camera provisions, and the Ultrasonic Front and Rear Park Assist suggest a truck that has adapted to the difficult science of parallel parking something very large. Skid plates, a 2-speed active transfer case, and the spray-on bedliner with Denali logo indicate this specimen is equally comfortable navigating a construction site or a corporate headquarters. Safety Alert Seat, Forward Collision Alert, Automatic Emergency Braking, Rear Cross Traffic Alert, and Trailer Side Blind Zone Alert are present for those moments when instinct alone is not quite enough.
This Sierra 3500HD Denali Ultimate is a rare find and our team would love to walk you through every detail in person. Give us a call at 978-228-5021 to ask questions or to schedule a test drive here at AutoFair Ford of Haverhill. We suspect, once you sit behind that leather steering wheel with the Duramax diesel idling beneath you, the decision will make itself.
