How much does the 2020 Mercedes-Benz G-Class cost?

Prices have softened 4.52% compared to this time last year, making it a favorable time to shop this model year.

There are 681 listings available, which gives you a meaningful amount of inventory to compare.

If you find a listing below $121,476, that's toward the low end of the year-round range and worth acting on quickly.

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.

You get a vehicle that blends serious ruggedness with Mercedes-Benz luxury and technology, and it still feels distinctive because of its old-school, boxy character. It also brings surprisingly good handling for something this tall and heavy, which helps it work as both a statement piece and a usable luxury SUV.

The trade-offs are clear: it is poor value for money, and it can feel a little too rugged for the price. That makes it best for you if you want a luxury SUV with real personality and capability rather than the most rational buy in the segment.

Only 31.1% of listings are priced as good or great deals, so you may need to shop selectively.

Is the 2020 Mercedes-Benz G-Class reliable?

The 2020 Mercedes-Benz G-Class is presented as a rugged, body-on-frame SUV with serious off-road hardware and a luxury-focused cabin, which suggests it is built for demanding use rather than softness. Its performance notes point to strong mechanical capability, including standard 4WD, a nine-speed automatic, and locking differentials, while the expert commentary also highlights that it remains composed on pavement despite its size.

For maintenance, the available information does not add any special ownership perk language beyond the vehicle’s premium positioning. For used buyers, the bigger long-term risk is that a six-figure SUV with complex hardware can become expensive to keep in top shape if it has been neglected.

What should I look for when buying a used 2020 Mercedes-Benz G-Class?

Accident-free inventory is solid at 78.7% — always verify the vehicle history report.

You should still check the history report carefully, because a clean listing percentage does not replace a proper records review. Prioritize a pre-purchase inspection that focuses on the drivetrain, suspension, and any signs of hard use, since this model is built to handle more than the average luxury SUV. Pay close attention to condition, because the cabin materials and equipment are a big part of what you are paying for.

Key things to evaluate:

• Trim level: The cabin is loaded with standard luxury touches such as leather upholstery, heated front and rear seats, three-zone automatic climate control, and 64-color ambient lighting, while available upgrades include Nappa leather, wood or carbon fiber trim, a heated steering wheel, and massaging front seats. The base setup already feels upscale, but you should check whether the example you are considering has the options you want.
• Powertrain: The standard setup uses a 4.0-liter twin-turbocharged V8 with 416 horsepower and 450 pound-feet of torque, paired with a nine-speed automatic and 4WD. An AMG version adds much more output, so make sure the badge matches the performance you expect.
• Safety package: Standard driver assistance includes adaptive cruise control with stop-and-go, automatic emergency braking, lane-keep assist, blind-spot monitoring, parking assist, and a driver-attention monitor. The lane-keep assist can be overly aggressive, so test that system carefully.
• Infotainment: You get a standard 12.3-inch infotainment display, Apple CarPlay, Android Auto, Bluetooth, and SiriusXM satellite radio. A second 12.3-inch digital instrument screen is available, and the system uses a controller rather than a touchscreen.
• Fuel efficiency: The EPA rates the G550 at 13 mpg city, 17 highway, and 14 combined.

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 without paying for the highest-output version. It still gives you the signature rugged character, standard 4WD, the twin-turbo V8, and the luxury cabin features that define the model.
• AMG G63: This is the one to choose if you want the most powerful and performance-focused version, with a much stronger twin-turbo V8 and the quickest acceleration in the lineup. It makes sense if you care more about maximum output than value.

The safety package is broad across the lineup, but you should still test the lane-keep assist because of its aggressive behavior.

Is now a good time to buy a used 2020 Mercedes-Benz G-Class?

This is a moderate market for selective buyers, so you should shop carefully and compare listings.

• Deal availability: 31.1% of listings are priced as good or great deals.
• Inventory: There are 681 listings available.
• Price trend: Prices have softened 4.52% compared with last year.
• Clean inventory: 78.7% of listings are accident-free.

If you find a listing below $121,476, 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 $121,485 sits slightly below last year's $127,239.

That price movement suggests the market has eased, which can help you buy more confidently now. For a future seller, it also means you should expect depreciation pressure if you pay too close to the top of the range today.

Because this model is expensive and niche, resale will likely depend heavily on condition, mileage, and equipment. A well-kept example with desirable options should hold up better than one that looks worn or has a rough history.

Is the 2020 Mercedes-Benz G-Class safe?

It earns a 7/10 safety score from our experts.

The G-Class gets a long list of safety features, including 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 windows, and adjusts the front-passenger seat if a crash seems imminent, plus Pre Safe Sound to help limit hearing damage.

The main caveat is lane-keep assist, which can behave aggressively and unexpectedly. Since there are no crash-test ratings cited here, you should lean more heavily on the vehicle’s active safety equipment and your own inspection of how those systems work in real driving.

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:

• 31.1% of listings are priced as good or great deals.
• Accident-free inventory is solid at 78.7% — always verify the vehicle history report.
• Price trend: Prices have softened 4.52% compared with last year.
• It combines rugged capability with luxury and technology while preserving the classic G-Class character.

Consider the 2019 if:

• At $106,367, the 2019 costs less than the current year's $121,485 average.
• It offers the same distinctive, luxury-focused G-Class personality at a lower price.

Consider the 2021 if:

• At $137,695, the 2021 costs more than the current year's $121,485 average.
• It adds a more sophisticated powertrain, mechanicals, and technology.

The bottom line: If you want the best balance of price, inventory, and the classic G-Class experience, the 2020 is the primary year to target. If you are especially price-sensitive, the 2019 is the smarter value play; if you want the newer-feeling setup and can spend more, the 2021 is the upgrade path.
