The owner feedback also points to a dependable-feeling driving experience, with praise for its engineering quality and smooth, powerful performance.

You should start with a vehicle history report so you can separate clean examples from ones with accident records. After that, prioritize a thorough pre-purchase inspection, especially on a luxury SUV where repairs can be expensive if something has been overlooked. Focus on overall condition, maintenance history, and whether the vehicle’s equipment and comfort features are working as expected.

If you find a listing below $18,130, that's toward the low end of the year-round range and worth acting on quickly.

What is the 2017 Mercedes-Benz GLS's resale value?

The current average of $18,130 sits slightly below last year's $20,076.

That price movement suggests the model has already absorbed some of its near-term depreciation, which can help future sellers if they buy at the right price. If you purchase near the lower end of the range and keep the vehicle in strong condition, you may be better positioned when it’s time to resell. Demand should also benefit from the GLS’s strong owner satisfaction and luxury three-row appeal.

Vehicles with strong owner satisfaction ratings, like this model year's 4.61/5, tend to retain buyer demand, which supports resale value over time.
