Dealer Description

Experience premium power, sophistication, and intelligent design with this 2020 GMC Sierra 1500 Denali 4WD. With only 62,907 miles and a single-owner history, this truck embodies refinement and capability in perfect balance. Finished in striking Silver with a luxurious Jet Black leather interior, the Sierra Denali commands attention with its bold stance and meticulous craftsmanship. The signature Denali grille, bright chrome 22-inch aluminum wheels (LPO), and Power Sunroof set the stage for a truck built to impress—whether on the highway or the job site. Under the hood, the powerful yet efficient 3.0L I6 Duramax Turbo Diesel Engine paired with a 10-speed electronically controlled automatic transmission delivers exceptional performance, smooth acceleration, and confident towing ability. Complemented by the ProGrade Trailering Package, Towing/Camper Package, and Trailer Tire Pressure Monitor System, this Sierra is ready for demanding tasks while maintaining the precision and comfort you expect from the Denali name. Inside, sophistication meets technology. The Premium GMC Infotainment System with Navigation and an 8-inch color touchscreen provide intuitive connectivity and entertainment, powered through the Bose Premium Stereo for concert-level sound. The cabin offers true comfort with premium materials and advanced features like Power Windows, Power Door Locks, Heated Exterior Mirrors, and Power Adjustable Mirrors. The Power Running Boards (GMC MultiPro Power Steps) offer easy, refined access to the cabin. Cutting-edge technology enhances every drive, including the Multicolor 15-inch Head-Up Display, Rear Camera Mirror, HD Surround Vision with trailer view, and a Bed View Camera.
