Accident-free inventory is excellent at 90.7% — clean inventory, standard diligence applies.

You should still run a vehicle history report and prioritize a pre-purchase inspection, especially if you’re shopping higher-trim trucks with more technology and convenience equipment. Focus on overall condition, feature operation, and signs of hard use, since this model can be configured as everything from a work truck to a luxury-leaning cruiser. If you want the most confidence, pay extra attention to how the truck’s tech, cabin materials, and parking aids have held up.

Key things to evaluate:

• Trim level: The base Pro keeps things simpler with a 7-inch touchscreen, Apple CarPlay, Android Auto, remote keyless entry, cloth seats, and Bluetooth, while the SLE adds a power-adjustable driver’s seat, heated front seats, a heated steering wheel, dual-zone automatic climate control, a wall-style power outlet, a fully digital instrument panel, a larger touchscreen, wireless Apple CarPlay and Android Auto, additional USB ports, and a Wi-Fi hotspot. The SLT adds leather upholstery, an auto-dimming rearview mirror, a power-adjustable front passenger seat, and memory settings for the driver’s seat. The Denali Ultimate is the most luxurious version described, with nearly every feature optional on other trims.
• Powertrain: The Sierra 1500 offers a gas 2.7-liter turbocharged four-cylinder, a 3.0-liter Duramax turbocharged inline-six diesel, a 5.3-liter V8, and a 6.2-liter V8. The diesel is described as lively, and the gas turbo-four is the efficiency-focused choice among the gas engines.
• Safety package: Standard equipment includes forward collision warning, automatic emergency braking, pedestrian detection, lane-departure warning, and GM’s Teen Driver system. Higher trims can add blind-spot monitoring, rear cross-traffic alert, front and rear parking sensors, adaptive cruise control, a surround-view camera system, GM’s Safety Alert seat, and Super Cruise. The most advanced safety content is concentrated on upper trims.

Which 2023 GMC Sierra 1500 trim should I buy?

The 2023 GMC Sierra 1500 is offered in 8 trim levels: Pro, SLE, Elevation, SLT, AT4, AT4X, Denali, and Denali Ultimate.

Here's the short version:

• Pro: This is the simplest choice if you want the most straightforward setup, including the carryover infotainment system and the basics you need without the added complexity of the higher trims.
• SLE: This is the best-value trim for many shoppers because it adds heated front seats, a heated steering wheel, dual-zone climate control, a larger touchscreen, wireless smartphone integration, and a Wi-Fi hotspot.
• Elevation: This trim keeps much of the SLE’s equipment while opening the door to more available options and packages, so it suits you if you want a more customized build.
• SLT: This is the step up if you want a more upscale cabin, thanks to leather upholstery, memory settings, and a power-adjustable front passenger seat.
• AT4: This is the off-road-oriented choice, with standard 4WD, skid plates, a lifted suspension, a two-speed transfer case, and an upgraded air filter.
• AT4X: This is the most trail-focused trim described, with steel bumpers, an integrated front winch, mud-terrain tires, additional skid plates, upgraded dampers, and locking differentials.
• Denali: This is the luxury-leaning pick if you want premium audio, ventilated front seats, wireless charging, and a bed-view camera.
• Denali Ultimate: This is the top-end choice if you want the most complete luxury and tech package, including massaging front seats, a 12-speaker Bose system, 22-inch wheels, and the integrated Kicker sound system.

The safety package expands as you move up the range, and the most advanced driver-assistance features are concentrated on the upper trims.
