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 they also value its spacious three-row layout and family-friendly mission.

Is the 2019 Mercedes-Benz GLS reliable?

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

The review summary also points to a vehicle that many owners describe as dependable and trouble-free in day-to-day use, especially when it comes to comfort and overall ownership experience. That said, some owners mention concerns about cost and rapid depreciation after 40,000 miles, so long-term ownership risk is more about value retention than widespread dissatisfaction. For used buyers, that means you should focus on maintenance history and overall condition to reduce the chance of expensive surprises.

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

At 70.2% 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 confirm accident records, title status, and service history before you get too far into the process. After that, prioritize a pre-purchase inspection, especially on suspension, electronics, and interior wear, since those areas matter most in a luxury SUV like this. You should also pay close attention to how the third row, cargo area, and cabin controls have held up, because condition can vary a lot from one listing to another.

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

This is a selective buyer’s market, so you can be choosy if you’re willing to compare listings and move quickly on the right one.

• Deal availability: 33.9% of listings are priced as good or great deals.

• Price trend: Prices have softened 11.69% compared with last year.
• Clean inventory: 70.2% of listings are accident-free.

If you find a listing below $23,735, 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 $23,818 sits slightly below last year's $26,971.

That decline suggests the market has already absorbed a meaningful amount of depreciation, which can help future sellers if prices stabilize from here. If you buy at a favorable price today, you may have less downside left than a shopper who paid closer to last year’s average. The model’s strong owner satisfaction can also help support demand when it’s time to resell.

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:

• 33.9% of listings are priced as good or great deals.
• At 70.2% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.
• Price trend: Prices have softened 11.69% compared with last year.
• Owners rate it 4.5/5 — a strong satisfaction signal.

The bottom line:

The 2019 is the right pick if you want the classic GLS formula: a spacious, comfort-focused luxury SUV with strong owner approval and a softer used-car price than last year. If you’re especially price-sensitive, you may also want to compare nearby years to see whether a lower-mileage or better-equipped alternative fits your budget better, but the 2019 remains the better value target when you want the balance of price, inventory, and owner satisfaction.
