Owners rate it 4.61/5, a strong signal of long-term satisfaction.

The owner feedback also points to a vehicle that feels well engineered, dependable in daily use, and satisfying over time, especially if you value comfort and strong performance. That said, used luxury SUVs can carry higher ownership risk if maintenance has been deferred, so you should pay close attention to service history and overall condition before buying.

At 64.2% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.

You should start with a vehicle history report and confirm whether any reported damage was repaired properly. A pre-purchase inspection should focus on bodywork quality, signs of prior collision repair, and the condition of major comfort and convenience features. Because this is a large luxury SUV, you should also pay close attention to how well the cabin, suspension, and electronics have aged.

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

The current average of $18,033 sits slightly below last year's $19,793.

That price movement suggests the model has already absorbed some depreciation, which can help future resale stability if you buy at the right price. If you keep the vehicle in strong condition and maintain it well, you may be better positioned when it comes time to sell. The current market also shows that buyers still respond to this SUV’s luxury appeal and three-row practicality.

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.

Should I buy a 2017 Mercedes-Benz GLS or consider a different year?

If you're weighing the 2017 against nearby model years, here's how to think about it:

Choose the 2017 if:

• 36.7% of listings are priced as good or great deals.
• At 64.2% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.
• Price trend: Prices have softened 8.89% compared with last year.
• Owners rate it 4.61/5 — a strong satisfaction signal.

The bottom line: If you want the strongest mix of value and owner satisfaction, the 2017 is the primary year to focus on, especially because prices have eased and there is still a meaningful pool of listings to compare. If you are especially price-sensitive, you can widen your search to nearby years, but the 2017 remains a sensible starting point when you want a well-regarded luxury SUV with a softer market price.
