At 63.1% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.

You should start with a vehicle history report so you can separate clean examples from those with prior damage. After that, prioritize a thorough pre-purchase inspection, especially for signs of wear in the suspension, interior, and electronics. Because this is a large luxury SUV, condition matters a lot: a well-maintained example is much easier to live with than one that has been deferred on service or repairs.

The current average of $18,084 sits slightly below last year's $19,881.

That price movement suggests the market has softened, which can help you buy more affordably now but may also limit short-term upside if you plan to resell soon. For a future seller, the key is to buy a clean, well-maintained example at a sensible price so you have less depreciation left to absorb. 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:

• 36.8% of listings are priced as good or great deals.
• At 63.1% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.
• Price trend: Prices have softened 9.04% compared with last year.
• Owners rate it 4.61/5 — a strong satisfaction signal.

The bottom line: If you want the better value play, the 2017 is the primary year to target because pricing has eased and owner satisfaction is strong. If you are especially price-sensitive, focus on the cleanest, best-documented examples rather than chasing the cheapest listing, since condition and history matter a lot in this segment.
