This 2021 GMC Sierra 1500 AT4 4x4 is a rugged yet refined pickup with only 59,000 miles, finished in Onyx Black with a premium Jet Black interior accented by Kalahari details. Powering this truck is the impressive 3.0L Duramax Turbo-Diesel inline-6 paired with a 10-speed automatic transmission, delivering excellent torque, efficiency, and towing confidence. The AT4 trim is purpose-built for off-road performance, equipped with the X31 Off-Road Suspension featuring a factory 2-inch lift, monotube shocks, skid plates, and hill descent control. The Autotrac 2-speed transfer case and automatic locking rear differential enhance traction in challenging conditions, while the integrated trailer brake controller and ProGrade Trailering System simplify towing. A spray-in bedliner with AT4 logo, hard folding tonneau cover, and multipro tailgate ensure the bed is as functional as it is durable. Inside, the cabin balances ruggedness with premium comfort. Heated and ventilated 10-way power front seats, heated rear seats, dual-zone climate control, and a heated leather-wrapped steering wheel elevate the driving experience. The AT4 Value Package adds a Bose premium sound system, navigation, wireless Apple CarPlay/Android Auto, wireless charging, memory settings, and a power sliding rear window for added convenience. Technology features include an HD color touchscreen with voice recognition, Bluetooth audio streaming, and multiple USB ports with SD card reader. Advanced safety features such as front and rear park assist, lane change alert with blind zone detection, rear cross-traffic alert, and a high-definition rear vision camera provide confidence on the road. On the exterior, bold design elements include signature LED lighting, fog lamps, red recovery hooks, 20-inch machined aluminum wheels with carbon grey accents, and dual exhaust with premium tips. Functional elements like CornerStep rear bumpers, LED cargo bed lighting, and 12 fixed tie-downs make it ready for work and adventure alike.

Disclaimers: At Certified AutoBrokers, the majority of our vehicles are purchased as new car trade-ins. Each vehicle goes through a top-tier detail and multi-point certification process to be deemed "Certified Pre-Owned" vehicles. We also replace any wearable items that are beyond 50% worn. This means, when you buy a car from us, you can be assured that you won't need new brake pads in 3 months or new tires for the winter. All of the cars we make available for sale are New York State inspected and in top condition. Our Certification ensures our vehicles operate at a higher standard, from being reconditioned and repaired to a higher standard, for you, the customer. If for any reason you are unhappy with your purchase within 3 days and/or 300 miles, we will swap out your vehicle. No questions asked. Our goal is to provide you with a purchasing experience you can count on (See "3 Day Exchange" on our website for details). Free Express Shipping is for customers within 300 miles; vehicles to be shipped farther will be quoted upon request.

Vehicle Merchandising: Vehicle options and details might be subject to human error on entry. Use for comparison purposes only. Please confirm actual details and options with Certified AutoBrokers. While every reasonable effort is made to ensure the accuracy of this information, we are not responsible for any errors or omissions contained on these pages.
Fuel Economy: Estimates are based on EPA mileage ratings. Use for comparison purposes only. Your actual mileage will vary depending on how you drive and maintain your vehicle.
Key Policy: Given that these are used vehicles and not new cars from the manufacturer, the quantity of keys provided is dependent on how many the vehicle was acquired with.

Pre-Auction Value Line Units: Over the years many of our customers have requested a line of more affordable vehicles, and we have listened by curating an inventory of what we refer to as our “Pre-Auction Value Line”. Pre-Auction vehicles have received a comprehensive, multi-point inspection from a Certified AutoBrokers certified technician to ensure they meet all NY safety standards and requirements. This check list will be provided at time of purchase with all the details of the work our shop completed as well as some non mandatory reccomendations we may have and their quote price. These vehicles are priced much lower than our traditional inventory, and as a result, they may show signs of regular wear and tear. Additionally, due to their age and mileage, Pre-Auction vehicles do not carry our Certified 3-month/3,000-mile warranty and are sold “as is.” Please note that Pre-Auction vehicles are intended for value-minded customers seeking more affordable transportation options. These vehicles have limited time availability and are priced to reflect their condition. For any additional questions about our Pre-Auction value program, please ask one of our sales advisors.
