CarGurus Analysis: 2020 Mercedes-Benz GLS
Summary
With 783 currently listed for sale and an average price of $30,974, 38.7% of 2020 Mercedes-Benz GLS listings on CarGurus are rated as good or great deals.
Favorably reviewed: Owners rated the 2020 Mercedes-Benz GLS 5 / 5 stars.
75.5% of 2020 Mercedes-Benz GLS listings on CarGurus are accident free.
Why it stands out
The 2020 Mercedes-Benz GLS stands out as the roomiest vehicle in the Mercedes-Benz lineup, with three rows of seating for six or seven people and up to 94 cubic feet of cargo space. It is positioned as a full-size SUV that blends the comfort and space of the S-Class luxury sedan with some off-road capability, which helps explain why it feels more like a luxury family hauler than a traditional truck-based SUV. For buyers who want a large Mercedes with genuine passenger and cargo flexibility, that combination is the GLS’s defining appeal.
For 2020, the second-generation GLS also moved to a curvier, smoother design language and a wide-screened, tech-forward cabin. The wheelbase was stretched by about two inches, and the body was just over 2.5 inches longer, while the base MSRP without options was $75,000 to $98,000. The GLS450 used a new six-cylinder engine with 362 horsepower and 369 pound-feet of torque, and its 48-volt mild hybrid system helped reduce fuel consumption and improve restart smoothness. Fuel economy rose to an EPA-estimated 21 mpg combined, and standard equipment included 4Matic all-wheel drive, Airmatic air suspension, dual 12.3-inch displays with MBUX, navigation, a Burmester surround sound stereo, wireless charging, and power-folding third-row seats.
The 2020 GLS also brought a long list of safety and convenience features, including Car-to-X communication, Exit Warning Assist, blind spot assist, 360-degree cameras, adaptive headlamps, auto high beams, and parking assist. That said, the tradeoff for the added comfort and technology was reduced front headroom and significantly less cargo space than before, and the model’s touch-sensing controls and third-row access remain among its drawbacks. Even so, the 2020 GLS is appealing because it delivers a polished, upscale experience with strong standard equipment and the kind of space that makes it especially useful for families.

Love all the features and it can pull my camper no problem! Beautiful car with kinetic seats that are nice when on a long drive. Love how my phone integrates into the dash screen. It’s classy for business but heavy enough to be outdoorsy as welll. Great value and you can’t go wrong with a Mercedes.

I just purchased a 2020 GLS 450 with 18,000 miles on the clock and I LOVE it. Nothing beats Mercedes when it comes to quality of vehicle and service from the Mercedes team. I was able to get an extended 5 year/ 100,000 mile warranty, which to me was worth the extra money. My last Mercedes was a 2003 E 500. It was such a good car that I waited this long to replace it. That’s what you get when you buy a Mercedes.

Is the 2020 Mercedes-Benz GLS a good car?
Yes — the 5/5 user rating points to strong owner satisfaction, and the GLS’s appeal is clear if you want a full-size luxury SUV with three rows, generous passenger space, and up to 94 cubic feet of cargo room. The overview also frames it as a family-focused luxury hauler with S-Class-like comfort and some off-road capability, so it fits best if you want comfort and flexibility more than truck-like ruggedness. With 39.6% of listings marked as good or great deals, you have a decent chance of finding a competitive price.
Is the 2020 Mercedes-Benz GLS reliable?
Owners rate it 5/5, a strong signal of long-term satisfaction.
The overview emphasizes a polished, upscale experience with strong standard equipment, including 4Matic all-wheel drive, Airmatic air suspension, and a long list of safety and convenience features. For used buyers, the main long-term ownership risk is that a large luxury SUV can be costly to keep in top condition, so maintenance history matters.
What should I look for when buying a used 2020 Mercedes-Benz GLS?
Accident-free inventory is solid at 75.2% — always verify the vehicle history report.
You should prioritize a history report first, then focus your inspection on signs of prior damage, uneven wear, or incomplete maintenance. Pay close attention to the condition of the third row, the touch-sensitive controls, and the suspension and electronics, since those are the kinds of systems that can affect ownership satisfaction in a luxury SUV.
Is now a good time to buy a used 2020 Mercedes-Benz GLS?
This is a moderate market, so you can be selective without expecting every listing to be a bargain.
- Deal availability: 39.6% of listings are priced as good or great deals.
- Inventory: There are 781 listings available.
- Price trend: Prices have softened 17.08% compared with last year.
- Clean inventory: 75.2% of listings are accident-free.
If you find a listing below $30,978, that's toward the low end of the year-round range and worth acting on quickly.
What is the 2020 Mercedes-Benz GLS's resale value?
The current average of $30,978 sits slightly below last year's $37,358.
That price movement suggests the market has already adjusted downward, which can help you as a buyer but may limit upside if you plan to resell soon. If you buy well and keep the vehicle in strong condition, you can reduce the impact of depreciation when it’s time to sell. Demand should remain supported by the GLS’s space, luxury positioning, and family-friendly utility.
Vehicles with strong owner satisfaction ratings, like this model year's 5/5, tend to retain buyer demand, which supports resale value over time.
Should I buy a 2020 Mercedes-Benz GLS or consider a different year?
If you're weighing the 2020 against nearby model years, here's how to think about it:
Choose the 2020 if:
- 39.6% of listings are priced as good or great deals.
- Accident-free inventory is solid at 75.2% — always verify the vehicle history report.
- Price trend: Prices have softened 17.08% compared with last year.
- Owners rate it 5/5 — a strong satisfaction signal.
Consider the 2021 if:
- At $45,367, the 2021 costs more than the current year's $30,978 average.
- It adds multiple powertrain options and more advanced technology.
The bottom line:
Choose the 2020 if you want the better value and are focused on luxury space, comfort, and family usefulness. Consider the 2021 if you want to spend more for newer tech and broader powertrain choice, but the 2020 is the smarter path for price-sensitive buyers.
