CarGurus Analysis: 2020 Mercedes-Benz GLS
Summary
With 196 currently listed for sale near New York, NY and an average price of $30,983, 26.0% of 2020 Mercedes-Benz GLSs for sale on CarGurus are rated as good or great deals.
Favorably reviewed: Owners rated the 2020 Mercedes-Benz GLS 5 / 5 stars.
70.9% of 2020 GLS models on CarGurus are accident free.
Why it stands out
The 2020 Mercedes-Benz GLS stands out as the roomiest vehicle in Mercedes-Benz’s lineup, with three rows of seating for six or seven people and up to 94 cubic feet of cargo space. It is also positioned as a midsize SUV that blends the comfort and space of the S-Class luxury sedan with some off-road capability, which helps explain its appeal to families who want luxury without giving up utility. For 2020, the GLS moved into a new generation with a curvier exterior, a wide-screened cabin, and a longer wheelbase and body, while also adding more comfort and safety features.
The 2020 GLS450 used a new six-cylinder engine with 362 horsepower and 369 pound-feet of torque, paired with a 48-volt mild hybrid system called EQ Boost. Mercedes said that setup improved fuel economy to an EPA-estimated 21 mpg combined, up from 18 mpg on the 2019 model. Standard equipment was generous, including dual 12.3-inch displays with MBUX, navigation, a Burmester surround sound stereo, wireless charging, power-folding third-row seats, power-adjustable second-row seats, and 19-inch wheels. Safety and convenience features such as blind spot assist, 360-degree cameras, adaptive headlamps, auto high beams, parking assist, Car-to-X communication, and Exit Warning Assist were also part of the package.
That said, the 2020 GLS was not without compromises. Front headroom decreased, and total cargo space fell significantly to 84.7 cubic feet. The pros and cons also point to touch-sensing controls, third-row seat access, and the AMG Line Package impeding entry and exit as drawbacks. Even so, the 2020 Mercedes-Benz GLS remains distinctive for combining genuine three-row practicality with a high level of luxury, strong standard technology, and a more efficient powertrain than before.

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. The 2020 GLS stands out as the roomiest vehicle in Mercedes-Benz’s lineup, with three rows of seating for six or seven people and up to 94 cubic feet of cargo space. It also blends S-Class-like comfort with utility, which makes it especially appealing if you want a luxury SUV that can handle family duty without feeling compromised. With 35.7% of listings marked as good or great deals, you have some room to shop selectively.
Is the 2020 Mercedes-Benz GLS reliable?
Owners rate it 5/5, a strong signal of long-term satisfaction.
The 2020 GLS adds a new generation’s worth of comfort and safety features, along with a more efficient mild-hybrid powertrain and generous standard equipment. That combination suggests a well-rounded ownership experience if you prioritize refinement and everyday usability. For used buyers, the main long-term risk is making sure the vehicle’s condition and maintenance history match its premium positioning.
What should I look for when buying a used 2020 Mercedes-Benz GLS?
Accident-free inventory is solid at 75.6% — always verify the vehicle history report.
You should prioritize a history report first, then focus on a thorough pre-purchase inspection. Pay close attention to the condition of the third-row access, touch-sensitive controls, and any signs of wear in the cabin and cargo area. Because this SUV is built around luxury and technology, you’ll want to confirm that all comfort, convenience, and safety features work as intended.
Is now a good time to buy a used 2020 Mercedes-Benz GLS?
This looks like a moderate, selective buyer’s market, so you can shop carefully and still find opportunities.
- Deal availability: 35.7% of listings are priced as good or great deals.
- Inventory: There are 742 listings available.
- Price trend: Prices have softened 15.07% compared with last year.
- Clean inventory: 75.6% of listings are accident-free.
If you find a listing below $32,729, 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 $32,740 sits slightly below last year's $38,550.
That price movement suggests the market has already adjusted downward, which can help future resale if you buy at the right number. If you pay close to the current average, your depreciation risk is likely lower than it would have been a year ago. Strong demand for a roomy, luxury three-row SUV can also help support values when the vehicle is well kept.
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:
- 35.7% of listings are priced as good or great deals.
- Accident-free inventory is solid at 75.6% — always verify the vehicle history report.
- Price trend: Prices have softened 15.07% compared with last year.
- Owners rate it 5/5 — a strong satisfaction signal.
Consider the 2021 if:
- At $47,956, the 2021 costs more than the current year's $32,740 average.
- It adds a more luxury-first character with multiple powertrain options.
The bottom line: If you want the better value, the 2020 is the stronger starting point because it combines a lower average price with solid deal availability and strong owner satisfaction. If you’re willing to spend more for a newer model-year experience, the 2021 is the better secondary path for buyers who prioritize a more upscale feel over price.
