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

Prices have softened 4.44% compared to this time last year, making it a favorable time to shop this model year.

There are 650 listings available, which suggests you have a meaningful amount of inventory to compare.

Is the 2020 Mercedes-Benz G-Class a good car?

The 2020 Mercedes-Benz G-Class earns a 7.17/10 expert rating, and its strongest category is Look and feel at 9/10.

The standout strength is Look and feel at 9/10.

It pairs premium interior materials with serious off-road capability, while still handling surprisingly well on pavement. That makes it a fit if you want a luxury SUV with real character and a distinctive presence, not just a status symbol.

The trade-offs are clear: it is poor value for money, and it can feel a little too rugged for the money.

With 35.1% of listings marked as good or great deals, there is some room to shop selectively.

Is the 2020 Mercedes-Benz G-Class reliable?

The 2020 Mercedes-Benz G-Class is presented as a rugged, mechanically serious SUV with a body-on-frame layout and standard four-wheel drive, which supports its long-term durability story. Its off-road hardware includes low range and front, center, and rear locking differentials, and the powertrain is described as strong and well suited to the vehicle’s mission.

The expert evaluation also notes that it handles backroads and highways well, with precise steering and a suspension setup that helps control body roll. On the ownership side, the cost-effectiveness discussion makes clear that this is not a low-cost vehicle to run, and fuel economy is poor by modern standards.

For used buyers, the main long-term risk is paying luxury-SUV money for a vehicle that can still be expensive to own and maintain.

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

Accident-free inventory is solid at 78.8% — always verify the vehicle history report.

You should still check the vehicle history report carefully and prioritize a pre-purchase inspection, especially on a truck with this price point and off-road hardware. Focus on overall condition, signs of hard use, and whether the equipment and trim level match the asking price.

Key things to evaluate:

• Trim level: The G-Class comes in two flavors, G550 and AMG G63. The G550 emphasizes the classic luxury-off-road balance, while the AMG G63 adds much more power and performance-oriented character. The base cabin already includes standard leather upholstery, heated front and rear seats, three-zone automatic climate control, and 64-color ambient lighting, so the main question is whether you want the extra performance and exclusivity of the AMG model.
• 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 souped-up twin-turbo V8 with 577 hp and 627 lb-ft of torque. Four-wheel drive and a nine-speed automatic transmission are standard, and the G550 is described as quick and strong enough for everyday driving.
• 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. Pre Safe can tighten the seatbelts, close windows, and adjust the front-passenger seat, and Pre Safe Sound is also included. Lane-keep assist can be overly aggressive, so that system deserves a close test drive.
• Infotainment: The standard setup includes a 12.3-inch infotainment display, Apple CarPlay/Android Auto, Bluetooth, and SiriusXM satellite radio with a six-month trial. A second 12.3-inch digital instrument screen is available, and the system uses a Comand controller rather than a touchscreen.
• Fuel efficiency: The EPA rates the G550 at 13 mpg city, 17 highway, and 14 combined. The AMG G63 gets 13 mpg city, 15 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 classic G-Class experience without paying for the AMG upgrade. It still gives you the twin-turbo V8, standard four-wheel drive, serious off-road hardware, and the full luxury cabin, so it covers the core appeal of the model very well.
• AMG G63: Choose this if you want the most powerful and most exclusive version. It adds a much stronger V8 and a more performance-focused personality, but it comes at a steep price premium.

The safety package is broad across the lineup, but lane-keep assist can be overly aggressive, so test that system carefully.

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

This is a moderate market for selective buyers, so you can shop carefully without expecting a deep bargain on every listing.

• Deal availability: 35.1% of listings are priced as good or great deals.
• Inventory: There are 650 listings available.
• Price trend: Prices have softened 4.44% compared with last year.
• Clean inventory: 78.8% of listings are accident-free.

If you find a listing below $119,584, 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 $119,584 sits slightly below last year's $125,145.

That decline suggests the market has eased a bit, which can help you buy more confidently now. If you plan to resell later, the G-Class still has strong identity and desirability, but its high purchase price and niche appeal can limit how quickly it recovers value. For a future seller, condition and equipment will matter a lot, especially on a vehicle this expensive.

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.

Standard safety 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. Mercedes’ Pre Safe system can tighten the seatbelts, close windows, and adjust the front-passenger seat, and Pre Safe Sound is also included.

One caveat is that lane-keep assist had a few false alarms and could react aggressively, so that system is worth testing on your own route.

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:

• 35.1% of listings are priced as good or great deals.
• Accident-free inventory is solid at 78.8% — always verify the vehicle history report.
• Price trend: Prices have softened 4.44% compared with last year.
• It blends rugged off-road capability with luxury and handles surprisingly well.

Consider the 2019 if:

• At $104,170, the 2019 costs less than the current year's $119,584 average.
• It delivers the redesigned G-Class look and upscale cabin at a lower price.

Consider the 2021 if:

• At $135,862, the 2021 costs more than the current year's $119,584 average.
• It adds a more modern luxury feel with strong power and sophisticated mechanicals.

The bottom line: If you want the best balance of price, character, and available inventory, the 2020 is the primary path to consider. If you are especially price-sensitive, the 2019 is the smarter value play, while the 2021 makes sense if you want to spend more for the newer-year alternative.
