What GMC Sierra 1500 do most buyers choose?

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

These higher-volume 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 sit close to the newest model years, so you often see a strong mix of features and availability.

What is the GMC Sierra 1500's resale value?

Most model years are down year over year, and the newer trucks show especially steep declines. That creates a more favorable setup for used buyers shopping recent model years, since the biggest price drops are concentrated near the top of the range. The older trucks show smaller changes, which suggests steadier pricing on those years.

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?
