How much does the 2019 Mercedes-Benz GLS cost?

Prices have softened 12.45% compared to this time last year, making it a favorable time to shop this model year.

There are 819 listings available, which gives you a solid amount of inventory to compare.

If you find a listing below $23,733.14, that's toward the low end of the year-round range and worth acting on quickly.

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 roomy three-row layout makes it especially appealing if you want a large SUV that prioritizes passenger space and everyday usability. The main tradeoffs are the poor gas mileage and the lack of updated electronics, so it fits you best if comfort and premium feel matter more than the latest tech. With 33.1% of listings marked as good or great deals, you still have room to shop selectively.

Is the 2019 Mercedes-Benz GLS reliable?

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

The owner feedback also points to a dependable-feeling ownership experience, with praise centered on comfort, smoothness, and the kind of luxury features you can count on day to day. At the same time, some owners mention poor gas mileage and rapid depreciation after 40,000 miles, so long-term ownership risk is more about value retention and running costs than outright satisfaction.

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 ones with prior damage. After that, prioritize a thorough pre-purchase inspection, especially if the listing price looks unusually attractive. Focus on overall condition, signs of wear, and whether the vehicle’s luxury features and interior equipment still work as expected.

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

The current average of $23,737 sits slightly below last year's $27,112.

That decline suggests the market has already absorbed a meaningful amount of depreciation, which can be helpful if you buy now and plan to sell later. For a future seller, that also means your best resale outcome will likely depend on buying well, keeping the vehicle in strong condition, and avoiding examples with accident history or heavy wear. A lower entry price can help cushion future depreciation if you choose carefully.

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:

• 33.1% 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 12.45% compared with last year.
• Owners rate it 4.5/5 — a strong satisfaction signal.

The bottom line: The 2019 GLS makes the most sense if you want the roomy, comfort-first version of this SUV and you can find a clean example at a strong price. If you’re especially price-sensitive, the 2019 is still worth considering because the market has softened, but you should be selective about condition and history before committing.
