Most model years are down year over year, and several recent ones show double-digit declines. That pattern can work in your favor if you’re shopping used, since it opens up more room to find a newer truck at a lower price than before. The biggest drops are concentrated in the newest model years, while older trucks are changing more slowly.
The 2014, 2018, and 2020 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 −13.78% versus a year ago, and the 2024 model is at −10.59%.
- Deal availability: The 2025 model has 39.1% good and great deals, and the 2024 model has 39.2%.
- Sweet-spot year: The 2023 model has the most listings at a current average price of $44,702. The GMC Sierra 1500 offers a premium-feeling cabin and a broad range of trims that make it easy to tailor the truck to your needs.
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, while the available 6.2-liter V8 makes 420 hp and 460 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 2023 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.

Why it stands out
The 2025 GMC Sierra 1500 stands out as a full-size pickup that leans upscale without losing its truck-first character. In its fifth generation, it is described as the more upscale of the GMC and Chevrolet full-size pickup siblings, with near-luxury cabin quality and the brand’s distinctive “We Are Professional Grade” identity. One of its most practical signature features is the MultiPro Tailgate, which adds a smaller hinged section that can pop up from the main gate to create different configurations and improve usefulness.
It also offers a broad range of powertrains and trims, which helps explain its appeal to buyers who want flexibility. The lineup includes turbocharged four-cylinder, V6, V8, and diesel options, along with rear- and four-wheel drive and multiple automatic transmissions depending on engine choice. Trim levels range from work-focused to luxury-oriented and off-road-focused, including Pro, SLE, Elevation, SLT, Denali, Denali Ultimate, AT4, and AT4X. The Denali and Denali Ultimate emphasize premium materials and styling, while the AT4X adds heavy-duty off-road hardware such as skid plates, beefed-up dampers, a two-speed transfer case, and all-terrain tires, plus 16-way power heated and ventilated front seats with a massage feature.
For shoppers, the 2025 Sierra 1500’s strengths are its upscale feel, strong capability, and wide spread of configurations. It is also noted as a pretty reliable truck in this generation, and the 2020 model in particular has earned lots of satisfied customers. The main tradeoff is cost: late used examples are expensive, and the Sierra’s many engine and trim combinations can be overwhelming.
