How much does the 2019 Mercedes-Benz GLS cost?

Prices have softened 12.90% compared to this time last year, making it a favorable time to shop this model year.

There are 805 listings available, which suggests you have a workable amount of inventory to compare.

If you find a listing below $23,798.83, 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 those strengths line up well with the GLS’s role as a roomy three-row SUV for families who want premium space and everyday usability. The same reviews also note that poor gas mileage and outdated electronics can take some shine off the experience, so it fits you best if comfort and cabin quality matter more than cutting-edge tech. With 35.3% of listings marked as good or great deals, you have some 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 review summary points to a vehicle that owners find smooth, comfortable, and dependable enough to keep them happy over time, especially when the focus is on luxury and everyday drivability. It also suggests that the GLS can be a trouble-free choice for buyers who value a refined ownership experience, though the concerns about cost and depreciation mean you should still shop carefully. For used buyers, the main long-term ownership risk is paying too much for a luxury SUV that may lose value quickly if condition and maintenance history are not strong.

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

At 70.6% 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 accident records or other red flags. After that, prioritize a pre-purchase inspection that focuses on body condition, signs of prior repair, and overall wear, since a luxury SUV like this can hide expensive issues behind a polished appearance. If possible, compare several listings side by side so you can judge whether the asking price matches the vehicle’s condition and history.

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

This looks like a moderate, selective buyer’s market, so you can shop with some leverage if you stay disciplined.

If you find a listing below $23,798.83, 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 $23,789 sits slightly below last year's $27,311.

That drop tells you the market has already absorbed a meaningful amount of depreciation, which can be good news if you are buying but less ideal if you are planning to sell soon. For a future seller, the key takeaway is that value retention may depend heavily on condition, mileage, and how well the vehicle has been maintained. A well-kept example should still attract interest from shoppers who want a spacious luxury SUV without paying new-model prices.

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:

• 35.3% of listings are priced as good or great deals.
• At 70.6% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.
• Price trend: Prices have softened 12.90% compared with last year.
• Owners rate it 4.5/5 — a strong satisfaction signal.

The bottom line: If you want the GLS’s roomy three-row layout, luxury feel, and strong owner approval at a lower market price, the 2019 is the primary year to target. If you are especially price-sensitive, focus on the cleanest, best-documented examples and compare them carefully against nearby years so you can decide whether the savings outweigh any condition or history concerns.
