What Mercedes-Benz GLS do most buyers choose?

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

Higher-volume years tend to be popular because they give you more inventory to compare, which can make it easier to find the right color, mileage, and price combination. They also often represent the sweet spot between newer features and broader availability.

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 newer model years are also seeing double-digit declines, so recent examples may offer stronger value than their original pricing suggests. The 2017, 2021, and 2023 model years have held their value best, with the smallest year-over-year price changes.

Should I buy a used Mercedes-Benz GLS now or wait for the next model?

Consider waiting if:

• Powertrain/efficiency: A turbocharged 3.0-liter inline-six provides 375 horsepower and 369 pound-feet of torque, and it’s EPA-rated at 21 mpg combined.
• Tech: Wireless Apple CarPlay and Android Auto and a navigation system with augmented reality enhancement are standard.
• Safety: Nearly 40 safety and driver-assistance systems appear on the 2026 GLS’ standard equipment list, including Mercedes’ innovative Pre-Safe, Crosswind Assist, and Active Emergency Stop Assist technologies.

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 2028 inventory to mature.
