What GMC Sierra 1500 do most buyers choose?

The GMC Sierra 1500 years with the most listings are 2025, 2023, and 2024.

These higher-volume model years tend to be popular because they give you more inventory to compare, which can make it easier to find the right trim, mileage, and price combination. They also tend to attract shoppers looking for newer features while still staying within the used market.

What is the GMC Sierra 1500's resale value?

Most model years are down year over year, and several recent ones are posting double-digit declines. That pattern gives used buyers more room to shop, especially if you are targeting newer trucks that have softened more sharply. The smaller declines on older model years suggest those trucks have been changing more gradually.

The 2014, 2015, and 2018 model years have held their value best, with the smallest year-over-year price changes.

Should I buy a used GMC Sierra 1500 now or wait for the next model?

Buy now if:

• Price trend: The 2025 model is at −14.27% versus a year ago, and the 2024 model is at −11.2%.
• Deal availability: The 2025 model has 32% good and great deals, and the 2024 model has 32.7%.
• Sweet-spot year: The 2025 model has the most listings at a current average price of $48,206. The GMC Sierra 1500 offers a premium-feeling cabin and a broad range of trims that make it easy to tailor the truck to work, comfort, or capability.

Consider waiting if:

• Powertrain/efficiency: Base models get a 2.7-liter turbocharged four-cylinder engine dubbed TurboMax that produces 310 horsepower and 430 pound-feet of torque, and the Duramax turbodiesel 3.0-liter inline-six produces 305 hp and 495 lb-ft.
• Tech: SLE and higher models get a 12.3-inch digital instrument cluster and a 13.4-inch touchscreen with wireless Apple CarPlay and Android Auto, as well as Google Built-In features.
• Safety: Denali and Denali Ultimate models can also be equipped with Super Cruise, GM’s hands-free driver-assistance system, and our test vehicle also had the recently added Super Cruise active lane-change feature.
• Starting price: Pricing starts at $39,595 for a base Pro model with RWD and no frills.

If you're buying used today, the 2025 model year offers the best mix of value and availability. If you want the latest tech and features, it may be worth waiting for the next model year's inventory to build up.
