CarGurus Analysis: 2020 Mercedes-Benz G-Class
overall

Summary
With 686 currently listed for sale and an average price of $120,854, 34.4% of 2020 Mercedes-Benz G-Class models for sale on CarGurus are rated as good or great deals.
Favorably reviewed: CarGurus experts gave it a 7.17 / 10.
80.0% of 2020 G-Class models on CarGurus are accident free.
Why it stands out
The 2020 Mercedes-Benz G-Class stands out because it blends ruggedness and luxury in a way few SUVs can match. It wears an anachronistic look and feel reminiscent of the Hummer H1, yet it also has the luxury and tech features of other Mercedes models. Mercedes gave the G-Class its first-ever redesign for the 2019 model year, but it tried to keep as much of the old G-Wagen’s character as possible.
That mix of old-school personality and modern polish is the G-Class’s main appeal. It offers premium interior materials, true off-road capability, and handling that is surprisingly good for something so rugged. The tradeoff is that it is poor value for money, and it can feel a little too rugged for the money.

Is the 2020 Mercedes-Benz G-Class a good car?
The 2020 Mercedes-Benz G-Class earns a 7.17/10 expert rating.
The standout strength is Look and feel at 9/10.
It blends ruggedness and luxury in a way few SUVs can match, with premium interior materials and true off-road capability. It also handles surprisingly well for something so rugged, which helps if you want a luxury SUV that still feels capable on pavement. The trade-offs are poor value for money and a cabin that can feel a little too rugged for the price.
There are 34.7% good or great deals in the market, so you have some room to shop selectively.
Is the 2020 Mercedes-Benz G-Class reliable?
The 2020 Mercedes-Benz G-Class is built around a rugged, body-on-frame design and a powertrain that’s meant to handle serious use. Its off-road hardware and straightforward mechanical character support the sense that it’s engineered for durability, while the luxury-focused cabin and technology add complexity you’ll want to keep an eye on over time.
The performance notes point to strong straight-line power, precise steering, and a suspension setup that helps control body roll. The cost-effectiveness notes also make clear that ownership is expensive, so long-term risk for used buyers is less about basic toughness and more about paying a lot to maintain a very costly SUV.
What should I look for when buying a used 2020 Mercedes-Benz G-Class?
Accident-free inventory is solid at 80.1% — always verify the vehicle history report.
You should still check the history report carefully and prioritize a pre-purchase inspection, especially on a vehicle this expensive and mechanically complex. Focus on overall condition, signs of hard use, and whether the truck has been maintained consistently, since the G-Class can attract buyers who use it very differently from a typical luxury SUV.
Key things to evaluate:
- Trim level: The cabin is defined by standard leather upholstery, heated front and rear seats, three-zone automatic climate control, and 64-color ambient lighting, while the AMG Line package adds flared wheel arches and a front push bar.
- Powertrain: The G550 uses a 4.0-liter twin-turbocharged V8 with 416 horsepower and 450 pound-feet of torque, while the AMG G63 uses a more powerful twin-turbo V8 with 577 hp and 627 lb-ft of torque.
- Safety package: Standard equipment includes adaptive cruise control with stop-and-go, automatic emergency braking, lane-keep assist, blind-spot monitoring, parking assist, and a driver-attention monitor.
- Infotainment: You get a 12.3-inch infotainment display, Apple CarPlay/Android Auto, Bluetooth, and SiriusXM satellite radio, with an available second 12.3-inch digital instrument screen.
- Fuel efficiency: The G550 is rated at 13 mpg city, 17 highway, and 14 combined, while the AMG G63 gets 15 mpg highway and the same city and combined ratings as the G550.
Which 2020 Mercedes-Benz G-Class trim should I buy?
The 2020 Mercedes-Benz G-Class is offered in 2 trim levels: G550, AMG G63.
Here's the short version:
- G550: This is the better-value choice if you want the core G-Class experience, including the standard V8, 4WD, locking differentials, and the full luxury cabin without stepping into AMG pricing.
- AMG G63: Choose this if you want the most powerful version and are willing to pay for the extra performance and exclusivity.
The safety package is standard across the lineup, so you do not need to move up a trim to get the core driver-assistance features.
Is now a good time to buy a used 2020 Mercedes-Benz G-Class?
This is a moderate market for selective buyers, so it makes sense to compare listings carefully and move quickly on the right one.
- Deal availability: 34.7% of listings are priced as good or great deals.
- Inventory: There are 688 listings available.
- Price trend: Prices have softened 4.50% compared with last year.
- Clean inventory: 80.1% of listings are accident-free.
If you find a listing below $120,778, that's toward the low end of the year-round range and worth acting on quickly.
What is the 2020 Mercedes-Benz G-Class's resale value?
The current average of $120,778 sits slightly below last year's $126,474.
That decline suggests the market has eased a bit, which can help you buy more confidently now. If you plan to sell later, the G-Class still has strong brand appeal, but your resale outcome will depend heavily on condition, mileage, and how well the truck has been kept. Because this is a high-priced SUV with a narrow buyer pool, clean history and strong presentation will matter a lot when it’s time to list it.
Is the 2020 Mercedes-Benz G-Class safe?
The 2020 G-Class hasn’t received crash-test ratings from the Insurance Institute for Highway Safety or National Highway Traffic Safety Administration.
It earns a 7/10 safety score from our experts.
It comes with adaptive cruise control with stop-and-go, automatic emergency braking, lane-keep assist, blind-spot monitoring, parking assist, and a driver-attention monitor. Mercedes also includes Pre Safe, which tightens the seatbelts, closes the windows, and adjusts the front-passenger seat if a collision seems likely, plus Pre Safe Sound to help limit hearing damage.
One caveat is that lane-keep assist can be overly aggressive and unexpectedly tug the steering wheel, so you should pay attention to how that system behaves during a test drive.
Should I buy a 2020 Mercedes-Benz G-Class 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:
- 34.7% of listings are priced as good or great deals.
- Accident-free inventory is solid at 80.1% — always verify the vehicle history report.
- Price trend: Prices have softened 4.50% compared with last year.
- It keeps the G-Class’s rugged character while pairing it with luxury and modern tech.
Consider the 2019 if:
- At $104,638, the 2019 costs less than the current year's $120,778 average.
- It delivers the redesigned G-Class experience at a lower price.
Consider the 2021 if:
- At $136,281, the 2021 costs more than the current year's $120,778 average.
- It adds a more sophisticated powertrain and technology.
The bottom line: If you want the best balance of price and the modern G-Class formula, the 2020 is the sweet spot. If you’re more price-sensitive, the 2019 is the smarter value play; if you want the newer-year upgrade and can spend more, the 2021 is the better step up.
