What Mercedes-Benz GLS do most buyers choose?

The Mercedes-Benz GLS years with the most listings are 2025, 2024, and 2023.

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

The table shows broad downward movement across the GLS lineup, which can work in your favor if you’re shopping used.

The smallest declines are still meaningful, but they show that some versions are holding value a bit better than others.

The 2017, 2021, and 2023 model years have held their value best, with the smallest year-over-year price changes.
