You should still run a vehicle history report and prioritize a pre-purchase inspection, especially on a heavy-duty truck that may have been used for towing or hauling. Focus on overall condition, signs of hard use, and whether the truck’s equipment works as intended. If you’re shopping a higher-trim example, make sure the luxury and tech features are functioning properly.

Key things to evaluate:

• Trim level: The top Denali Ultimate trim adds a more upscale cabin, standard LED lighting, sequential turn signals, the MultiPro Tailgate, and a six-passenger Crew Cab setup, while lesser trims make do with a smaller 8.0-inch touchscreen.
• Powertrain: The truck uses a 6.6-liter Duramax turbocharged diesel V8 with 470 horsepower and 975 pound-feet of torque, paired with a 10-speed Allison automatic transmission and standard four-wheel drive.
• Safety package: It comes standard with automatic emergency braking, forward collision warning, lane departure warning, front and rear parking sensors, a surround-view parking camera, pedestrian detection, rear cross-traffic alert, blind-spot monitoring, and a rear-facing cargo bed camera.
• Infotainment: The Denali Ultimate features a 13.4-inch screen, wireless Apple CarPlay and Android Auto, Google built-in, wireless device charging, a 15-inch head-up display, and split-screen navigation.
• Fuel efficiency: During long highway stints, the diesel returned as much as 21 miles per gallon, while suburban and city driving could dip into the single digits.

That price movement suggests the market has cooled a bit, which can help you as a buyer today but may also mean future sellers need to be realistic on asking price.
