What Mercedes-Benz GLS do most buyers choose?

The Mercedes-Benz GLS years with the most listings are 2025, 2022, and 2021.

Higher-listing model years tend to draw more shopper attention because they give you more inventory to compare, which can make it easier to find the right trim, colour, and price. They also often become the most practical starting point when you want a balance of selection and value.

What is the Mercedes-Benz GLS's resale value?

The table shows broad downward movement across the GLS lineup, with every listed model year posting a negative year-over-year change.

The smaller declines at the lower end of the table suggest some years have softened less than others.

The 2021, 2019, and 2018 model years have held their value best, with the smallest year-over-year price changes.
