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

Prices have softened 4.65% compared to this time last year, making it a favorable time to shop this model year.

There are 684 listings available, which gives you a meaningful amount of inventory to compare before you buy.

If you find a listing below $121,577.24, 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 the appeal is rooted in its old-school personality and distinctive, anachronistic character. It also brings premium interior materials and surprisingly good handling for something this tall and heavy.

The trade-offs are clear: it is poor value for money, and it can feel a little too rugged for the price. The aggressive lane-keep assist is another drawback.

If you want a luxury SUV with real personality and true off-road credibility, this is aimed squarely at you. The market still shows 27.8% good or great deals, so there is some room to shop carefully.

Is the 2020 Mercedes-Benz G-Class reliable?

The 2020 Mercedes-Benz G-Class is presented as a rugged, body-on-frame SUV with a reputation for capability and refinement in equal measure. Its off-road hardware is substantial, and the expert notes that it feels rock solid on the highway despite its tall, broad shape.

The performance notes also point to a durable, old-school character: it uses body-on-frame construction, standard 4WD, and locking differentials front, center, and rear. That setup supports serious use, but it also reinforces the truck-like nature of the vehicle.

Mercedes includes a long list of protective features, including Pre Safe systems that tighten seatbelts, close windows, and adjust the front-passenger seat in a crash scenario. For used buyers, the main long-term risk is that this kind of complex, high-end hardware can be expensive to live with if prior maintenance or repairs were neglected.

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

Accident-free inventory is solid at 80.4% — always verify the vehicle history report.

You should still check the vehicle 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, electronics, and any signs of hard off-road use. Pay close attention to cabin wear, since the G-Class mixes luxury materials with a rugged mission.

Key things to evaluate:

• Trim level: The cabin is loaded with standard luxury touches like 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 is already rich, but the optional AMG Line package adds a more aggressive look.
• 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. Four-wheel drive and a nine-speed automatic are standard.
• Safety package: Standard driver aids include 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 adds crash-prep functions, but lane-keep assist can be overly aggressive.
• Infotainment: You get a standard 12.3-inch infotainment display, Apple CarPlay/Android Auto, Bluetooth, and SiriusXM 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 core G-Class experience without paying extra for the AMG badge. It still gives you the signature rugged character, strong V8 power, standard 4WD, serious off-road hardware, and a richly appointed cabin.
• AMG G63: Choose this if you want the most powerful version and are willing to pay for it. It adds a much stronger twin-turbo V8 and the highest-performance character in the lineup, but it is the pricier route.

The safety package is broad 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 it makes sense to compare listings carefully and move quickly on the right one.

• Deal availability: 27.8% of listings are priced as good or great deals.
• Inventory: There are 684 listings available.
• Price trend: Prices have softened 4.65% compared with last year.
• Clean inventory: 80.4% of listings are accident-free.

If you find a listing below $121,577.24, 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 $121,532 sits slightly below last year's $127,460.

That price movement suggests the market has eased, which can help you buy more confidently today. If you own one, it also means your resale position is softer than it was a year ago.

For a future seller, the key takeaway is that this model still commands strong attention, but pricing has moved down enough that you should expect more competition. A well-kept example with clean history and desirable equipment should hold up better than a rough one.

Is the 2020 Mercedes-Benz G-Class safe?

The 2020 G-Class hasn’t received crash-test ratings from IIHS or 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 tightens the seatbelts, closes windows, and adjusts the front-passenger seat if a collision seems likely.

One caveat is that lane-keep assist can be overly aggressive and has produced false alarms. That means you should test the system on your own drive and make sure it behaves the way you want.

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:

• 27.8% of listings are priced as good or great deals.
• Accident-free inventory is solid at 80.4% — always verify the vehicle history report.
• Price trend: Prices have softened 4.65% compared with last year.
• It keeps the redesigned G-Class formula with strong off-road capability and a luxury cabin.

Consider the 2019 if:

• At $107,655, the 2019 costs less than the current year's $121,532 average.
• It offers the first redesigned G-Class with strong personality and upscale appeal.

Consider the 2021 if:

• At $138,381, the 2021 costs more than the current year's $121,532 average.
• It adds a more sophisticated powertrain and technology package.

The bottom line: If you want the best balance of price, inventory, and the redesigned G-Class experience, the 2020 is the primary target. If you are especially price-sensitive, the 2019 is the cheaper path into the same basic character, while the 2021 makes sense only if you want to spend more for the newer-year premium.
