Vehicle Description
Looking for a truck that works hard, plays harder, and looks downright mean while doing it? Meet the 2021 GMC Sierra 1500 AT4, a beast in Satin Steel Metallic with all the rugged charm and brawn you need to turn heads at every stoplight. With 68,123 miles on the odometer, this truck has just enough road experience to prove its worth...without stealing all the fun for itself.Under the hood, you've got the 3.0L I-6 Diesel Turbocharged engine, an absolute powerhouse that laughs in the face of heavy loads and long hauls. Paired with a 10-speed automatic transmission and four-wheel drive, this Sierra is ready to take on mud, snow, or the soul-crushing stop-and-go traffic of Monday morning commutes. And let's not forget the locking/limited slip differential...because why should the fun stop when the pavement does?GMC didn't just build this truck for muscle; they gave it brains and style too. The leather-appointed seats, heated mirrors, and multi-zone climate control keep you riding in comfort, while the WiFi hotspot and power everything make sure you're connected and cruising in style. Need to load up? The Corner-Step rear bumper, integrated tailgate step, and factory bed liner make sure you can handle anything from worksite equipment to that new couch your buddy swore would fit in his sedan.Safety? You bet. With front, side, and rear airbags, stability and traction control, hitch guidance, and a rear seat reminder (because leaving your snacks behind is a tragedy), this truck has your back. Speaking of towing, the trailering package and ProGrade Trailering System make sure you can haul with confidence...whether its a boat, camper, or just a really heavy ego.This Sierra isn't just another truck. It's an adventure waiting to happen. Don't let it sit still too long...schedule a test drive today and see why this AT4 is the off-road king you never knew you needed!Search
