How much does the 2019 Mercedes-Benz GLS cost?

Prices have softened 13.00% compared to this time last year, making it a favorable time to shop this model year.

There are 843 listings available, which gives you a solid pool to compare prices and condition.

Is the 2019 Mercedes-Benz GLS a good car?

Yes — the 2019 Mercedes-Benz GLS earns a 4.5/5 user rating, which points to strong owner satisfaction. Owners consistently praise the smooth ride, comfort, and luxury features, and the GLS’s family-first layout makes it appealing if you want a large three-row SUV with a premium feel. The main tradeoffs are the dated electronics and poor gas mileage, so it fits you best if comfort, space, and traditional Mercedes luxury matter more than efficiency or the newest tech. With 37.6% of listings marked as good or great deals, there is meaningful market opportunity if you shop carefully.

Is the 2019 Mercedes-Benz GLS reliable?

Owners rate it 4.5/5, a strong signal of long-term satisfaction.

Owner feedback also points to a dependable, trouble-free ownership experience centered on comfort and luxury rather than frequent complaints about major issues. The strongest reliability takeaway for you is that this model tends to reward buyers who prioritize a well-kept example, since long-term ownership risk is more about maintenance costs and depreciation than a lack of owner confidence.

What should I look for when buying a used 2019 Mercedes-Benz GLS?

At 70.8% 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 or repeated claims. After that, prioritize a thorough pre-purchase inspection, especially for signs of wear in the suspension, electronics, and interior condition. Because this is a luxury three-row SUV, you should focus on how well the cabin, features, and ride quality have been maintained rather than just mileage alone.

Is now a good time to buy a used 2019 Mercedes-Benz GLS?

This is a moderate market for selective buyers, so you can find value if you compare listings carefully and move quickly on the right one.

• Deal availability: 37.6% of listings are priced as good or great deals.
• Inventory: There are 843 listings available.
• Price trend: Prices have softened 13.00% compared with last year.
• Clean inventory: 70.8% of listings are accident-free.

If you find a listing below $22,818, that's toward the low end of the year-round range and worth acting on quickly.

What is the 2019 Mercedes-Benz GLS's resale value?

The current average of $22,818 sits slightly below last year's $26,227.

That decline suggests the market has already adjusted downward, which can help you buy at a more favorable entry point. For a future seller, that also means resale value may remain sensitive to condition, mileage, and maintenance history rather than just model-year desirability. If you buy well and keep the vehicle in strong shape, you may be better positioned to limit further depreciation.

Vehicles with strong owner satisfaction ratings, like this model year's 4.5/5, tend to retain buyer demand, which supports resale value over time.

Should I buy a 2019 Mercedes-Benz GLS or consider a different year?

If you're weighing the 2019 against nearby model years, here's how to think about it:

Choose the 2019 if:

• 37.6% of listings are priced as good or great deals.
• At 70.8% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.
• Price trend: Prices have softened 13.00% compared with last year.
• Owners rate it 4.5/5 — a strong satisfaction signal.

The bottom line: You should lean toward the 2019 if you want the older GLS formula at a lower price and you value comfort, space, and luxury over the newest tech. If you are especially price-sensitive, a nearby year may also be worth comparing, but the 2019 stands out when you want a strong mix of owner satisfaction and softened pricing.
