This 2023 GMC Sierra 1500 AT4 is a one-owner, well-maintained example of GMC's rugged yet refined off-road capable half-ton pickup, with only 43,581 miles.

With its 4x4 capability and purposeful design, this truck is ready for adventure and everyday use alike.
Under the hood sits the 3.0 L Turbo Diesel six-cylinder engine paired with a 10-speed automatic transmission. This Duramax-powered configuration delivers a strong balance of torque and efficiency, offering excellent low-end pulling power and smooth highway cruising characteristics that have made the Duramax diesel a popular choice among Sierra owners. The diesel 1500 lineup is known for good torque output and respectable fuel economy for a full-size truck, and the 10-speed automatic helps make full use of the power delivery on and off the pavement.
Inside, the Sierra AT4 blends rugged capability with modern comfort. The cabin is built around user-friendly technology and premium materials, with available large touchscreens, digital driver displays, and intuitive infotainment features elevating the daily driving experience. Combined with its strong tow and payload ratings, the AT4's mix of off-road readiness, diesel efficiency, and refined interior features make this 2023 Sierra 1500 AT4 a versatile and desirable choice for enthusiasts who want capability without compromise.

Garage Kept Motors, LLC specializes in classic and specialty online auto sales.
For our consignors, we are the only auto brokers that offer a Transparent Sale Disclosure. This means, when a car sells, we provide an exact copy of the Bill of Sale. We do this so our clients know exactly who bought their car, where it went, and most importantly how much we sold it for. No funny business.
For our buyers, our vehicles are listed on the Internet, with over 100 photos, including undercarriage pictures, and walk-around videos of the vehicles running plus a narrative-style write-up of the cars history and features. Our international exposure allows us to sell cars across the globe, and we sell a majority of them out of state and overseas. We deliver honesty and consistency in our photos and descriptions, a “no surprise” approach, so buyers, both near and far, can invest with confidence sight unseen. We are not a gallery. Vehicles can be seen locally by appointment as potential buyers are given our undivided attention.
