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

Prices have softened 4.35% compared to this time last year, making it a favorable time to shop this model year.

There are 679 listings available, which gives you 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 appeal is rooted in the way it blends old-school character with modern luxury and tech. The standout strength is Look and feel at 9/10.

It delivers premium interior materials, true off-road capability, and handling that is surprisingly good for something so rugged. The trade-offs are poor value for money and a cabin that can feel a little too rugged for the price.

If you want a luxury SUV with a distinctive personality and serious capability, this one makes a strong case. 35.2% of listings are priced as good or great deals, so there are at least some attractive opportunities in the market.

Is the 2020 Mercedes-Benz G-Class reliable?

The 2020 Mercedes-Benz G-Class is built around a rugged body-on-frame layout and a serious off-road hardware set, which supports its long-term durability story. Its performance notes also point to a vehicle that feels rock solid on the highway, even with its tall stance and broad sides.

The expert notes also describe the G-Class as having the tools for serious off-roading, including low range and locking differentials, which reinforces its tough mechanical character. On the ownership side, the cost-effectiveness notes make clear that this is a six-figure SUV with gas-guzzling fuel economy, so long-term ownership risk for used buyers is less about basic toughness and more about expensive running costs.

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

Accident-free inventory is solid at 79.5% — always verify the vehicle history report.

You should still check the history report carefully, because a clean title does not tell you how hard the vehicle has been used. A thorough pre-purchase inspection matters here, especially if the SUV has seen off-road use or has expensive options fitted. Focus on overall condition, interior wear, and signs that the vehicle has been driven like the rugged luxury SUV it is.

Key things to evaluate:

• Trim level: The G-Class comes in two flavors, and the AMG G63 adds a much more powerful version of the twin-turbo V8. The base G550 already brings 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 souped-up version with 577 hp and 627 lb-ft of torque. Four-wheel drive and a nine-speed automatic transmission are standard, and the G550 also returns 13 mpg city, 17 highway, and 14 combined.
• Safety package: The standard suite 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 the windows, and adjust the front-passenger seat, and Pre Safe Sound is also included. Lane-keep assist can be overly aggressive.
• 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.

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 twin-turbo V8, standard 4WD, serious off-road hardware, and the luxury cabin features that define the model.
• AMG G63: Choose this if you want the most powerful version and are willing to pay for it. It brings a much stronger V8 and the highest-performance character in the lineup, but it sits at the top of the price range.

The standard safety package is broad, but lane-keep assist can be overly aggressive, so that is worth checking during a test drive.

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

This looks like a moderate buyer’s market, so you can shop selectively and still find worthwhile listings.

• Deal availability: 35.2% of listings are priced as good or great deals.
• Inventory: There are 679 listings available.
• Price trend: Prices have softened 4.35% compared with last year.
• Clean inventory: 79.5% of listings are accident-free.

If you find a listing below $121,199, 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 $121,199 sits slightly below last year's $126,707.

That price movement suggests the market has cooled a bit, which can help you as a buyer today. For a future seller, it means you should expect depreciation pressure rather than a strong appreciation story. The G-Class still has strong brand appeal, but the current trend shows that used pricing is not immune to softening.

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.

The standard driver-assistance suite 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 includes Pre Safe, which can tighten the seatbelts, close the windows, and adjust the front-passenger seat, plus Pre Safe Sound to help limit hearing damage.

One caveat is that lane-keep assist can react too aggressively and unexpectedly, so that system is worth evaluating carefully on your 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:

• 35.2% of listings are priced as good or great deals.
• Accident-free inventory is solid at 79.5% — always verify the vehicle history report.
• Price trend: Prices have softened 4.35% compared with last year.
• The 2020 keeps the G-Class’s rugged character while pairing it with modern luxury and tech.

Consider the 2019 if:

• At $104,650, the 2019 costs less than the current year's $121,199 average.
• It delivers the same core redesign-era appeal at a lower price.

Consider the 2021 if:

• At $136,444, the 2021 costs more than the current year's $121,199 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 sensible default. If you are especially price-sensitive, the 2019 is the cheaper path into the same basic experience, while the 2021 makes sense only if you want to spend more for the newer-year upgrade.
