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

Prices have softened 5.46% compared to this time last year, making it a favorable time to shop this model year.

There are 635 listings available, which gives you a meaningful pool to compare before you commit.

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

The 2020 Mercedes-Benz G-Class earns an expert rating of 7.2/10.

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

You get a rare mix of rugged character and luxury, with premium interior materials, strong off-road capability, and surprisingly good handling for a body-on-frame SUV. It also fits shoppers who want a distinctive, old-school presence rather than a conventional luxury SUV.

The main trade-offs are poor value for money and a cabin that can feel a little too rugged for the price.

With 32.4% of listings marked as good or great deals, 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 formula, and the expert review emphasizes that it still has true off-road capability while delivering a premium cabin and solid on-road manners. That combination suggests a vehicle engineered for durability and character rather than easygoing everyday efficiency.

The performance notes also point to a stout drivetrain and standard four-wheel drive, which reinforces its hard-use personality. On the ownership side, the cost-effectiveness commentary makes clear that this is a six-figure SUV with high running costs, so long-term ownership risk for used buyers is less about basic toughness and more about expensive upkeep and fuel use.

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

Accident-free inventory is solid at 78.9% — always verify the vehicle history report.

You should still run a history report on any candidate and prioritize a pre-purchase inspection, especially on a vehicle with this price point and off-road hardware. Focus on overall condition, signs of hard use, and whether the cabin and exterior show wear that matches the mileage.

Key things to evaluate:

• Trim level: The cabin is the biggest differentiator, with standard leather upholstery, heated front and rear seats, three-zone automatic climate control, and 64-color ambient lighting. The AMG Line package adds flared wheel arches and a front push bar, while Nappa leather, wood or carbon fiber trim, a heated steering wheel, and massaging front seats are available.
• Powertrain: The G-Class comes with a 4.0-liter twin-turbocharged V8 making 416 horsepower and 450 pound-feet of torque, plus standard four-wheel drive and a nine-speed automatic transmission. The performance notes also highlight strong straight-line punch and serious off-road hardware.
• 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 adds a pink-noise function.
• 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 Mercedes’ Comand controller rather than a touchscreen.
• Fuel efficiency: The EPA rates the G550 at 13 mpg city and 17 highway.

Which 2020 Mercedes-Benz G-Class trim should I buy?

The 2020 Mercedes-Benz G-Class is offered in 2 trim levels: G550 and AMG G63.

Here's the short version:

• G550: This is the trim that best captures the G-Class experience without pushing all the way into the highest price bracket. You still get the core appeal: the boxy design, premium cabin, serious off-road hardware, and strong on-road performance. It is the best-value choice if you want the character and capability without paying for the most extreme version.
• AMG G63: This is the more powerful, more expensive choice for buyers who want the most performance and the most presence. It adds a souped-up twin-turbo V8 and is the right pick if you care more about maximum output than value.

The safety package is generous across the lineup, but lane-keep assist can be overly aggressive.

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 before moving quickly.

• Deal availability: 32.4% of listings are priced as good or great deals.
• Inventory: There are 635 listings available.
• Price trend: Prices have softened 5.46% compared with last year.
• Clean inventory: 78.9% of listings are accident-free.

If you find a listing below $118,065, 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 $118,065 sits slightly below last year's $124,888.

That softer pricing suggests the market has cooled a bit, which can help you buy more selectively today. For a future seller, it also means you should expect resale value to depend heavily on condition, mileage, and how well the vehicle has been maintained.

Because the G-Class is a niche luxury SUV with strong character, well-kept examples should remain desirable. Still, the current trend shows that buyers are not paying quite as much as they were a year ago.

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 (IIHS) or National Highway Traffic Safety Administration (NHTSA).

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

The G-Class 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 also adds Pre Safe, which can tighten the seatbelts, close windows, and adjust the front-passenger seat, plus Pre Safe Sound to help limit hearing damage.

One important caveat is that lane-keep assist had a few false alarms and could react aggressively.

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:

• 32.4% of listings are priced as good or great deals.
• Accident-free inventory is solid at 78.9% — always verify the vehicle history report.
• Price trend: Prices have softened 5.46% compared with last year.
• The 2020 keeps the G-Class’s rugged character, premium cabin, and surprisingly good handling.

Consider the 2019 if:

• At $105,792, the 2019 costs less than the current year's $118,065 average.
• It emphasizes an unmistakably rugged presence with an upscale cabin.

Consider the 2021 if:

• At $135,217, the 2021 costs more than the current year's $118,065 average.
• It adds a more sophisticated powertrain, mechanicals, and technology.

The bottom line: The 2020 is the sweet spot if you want the classic G-Class formula with a softer market price than the newer model year. If you’re more price-sensitive, the 2019 is the better value play; if you want the newer-tech direction, look to the 2021.
