=== RUGGED, CAPABLE, OFF-ROAD-READY, NO-ACCIDENT, LOCALLY OWNED, NONSMOKER, TRAIL-TAMING PREMIUM MUSCLE! === This 2021 GMC Sierra 1500 AT4 is the full-size pickup that blends premium comfort with genuine off-road hardware. Finished in Satin Steel Metallic and riding on 20-inch machined aluminum wheels with Carbon Grey Metallic accents and all-terrain tires, it teams a 355-horsepower 5.3L V8 with four-wheel drive, a factory off-road suspension and a set of off-road assist steps that make climbing aboard easy. CARFAX reports no accidents or damage, a locally owned history in New Jersey and four service history records, including dealer maintenance inspections and oil changes. This Sierra was also previously sold as a GMC Certified Pre-Owned vehicle, and GMC certified powertrain protection and rust-through coverage remain in place through July 2027. === WHY SHOPPERS BUY THIS MODEL === The Sierra 1500 is the full-size pickup for buyers who want a truck with a more premium attitude. Cross-shopped against the Ford F-150, Chevrolet Silverado and Ram 1500, it stands out with a refined, upscale cabin, a smooth and confident ride, a wide range of capable powertrains and the professional-grade styling GMC is known for. Just as important is its everyday versatility. The Sierra works as a family vehicle during the week and a hauler or tow rig on the weekend, with a roomy crew cab, a deep and usable bed and the kind of engineering that makes a big truck feel manageable in town and relaxed on the highway. === AUTOMOTIVE PRESS AND INDUSTRY RECOGNITION === Kelley Blue Book gives the 2021 Sierra 1500 an expert rating of 4.2 out of 5, describing it as a truck with a professional yet premium attitude and crediting its innovative hardware and technology for work or play. That blend of upscale feel and real capability is exactly what the AT4 trim is built around. === WARRANTY === The odometer currently reads 14,946 miles. This Sierra is STILL COVERED by transferable GMC factory warranty protection, measured from an estimated in-service date of July 2021. === Remaining Transferable Factory Coverage === * GMC Certified Pre-Owned Powertrain Limited Warranty: 6 years or 100,000 miles, whichever comes first, running through July 2027.

Extended service plans are available for owners who want protection beyond these factory terms. === STANDARD FEATURES === The Sierra 1500 AT4 is GMC's off-road-minded Sierra, built for buyers who want real capability without giving up premium comfort.

Inside, the AT4 brings upscale touches that make long days comfortable, including leather-appointed seating with heated and ventilated front seats, a heated steering wheel and 10-way power front seats with driver memory, paired with the strong, familiar power of the 5.3L V8. === INSTALLED OPTIONS === === Standalone Features === * 20-inch machined aluminum wheels with Carbon Grey Metallic accents * Give the AT4 a bolder, more purposeful stance, with machined faces and dark accents that pair well with the all-terrain tires. * Off-road assist steps * Make getting in and out of the tall AT4 easier for drivers and passengers, and help you reach items in the bed and roof area. === TRUCK CAPABILITY === Capability figures below are for the factory configurati
