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.

It blends serious ruggedness with the luxury and technology you expect from Mercedes-Benz, and it still delivers true off-road capability. The trade-offs are clear: it is poor value for money and a little too rugged for the money, and the lane-keep assist can be overly aggressive. For you, that means the G-Class makes the most sense if you want a distinctive luxury SUV with real capability rather than a rational value play.

Only 31.8% of listings are priced as good or great deals, so you may need to be selective.

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 luxury interior and a powertrain built for both pavement and off-road use. Its performance notes point to strong straight-line power, standard 4WD, and serious trail hardware, while the overview emphasizes that it preserves old-school character in a thoroughly redesigned package.

The performance write-up also suggests it can handle highway and backroad driving better than its size and shape might imply, which is a good sign for everyday usability. On the cost side, the model’s six-figure pricing and gas-guzzling fuel economy mean ownership can be expensive even before maintenance and insurance. For used buyers, the long-term risk is less about basic toughness and more about whether you are prepared for high running costs and the possibility of expensive repairs on a complex luxury SUV.

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

Accident-free inventory is solid at 80.5% — always verify the vehicle history report.

You should start with the history report, then prioritize a pre-purchase inspection that checks for accident damage, uneven wear, and signs of hard use. Because this model is both luxury-focused and genuinely off-road capable, condition matters a lot: look closely at the interior, suspension, and any evidence of trail abuse or neglected maintenance.

Key things to evaluate:

• Trim level: The cabin is rich even in standard form, with leather upholstery, heated front and rear seats, three-zone automatic climate control, and 64-color ambient lighting. Available upgrades include Nappa leather, wood or carbon fiber trim, a heated steering wheel, and massaging front seats.
• Powertrain: The base G550 uses a 4.0-liter twin-turbocharged V8 with 416 horsepower and 450 pound-feet of torque, while the AMG G63 adds 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 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.
• Infotainment: The standard setup includes a 12.3-inch infotainment display, Apple CarPlay, Android Auto, Bluetooth, and SiriusXM. A second 12.3-inch digital instrument screen is available, and the system does not use 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:

• Base trim: The G550 gives you the core G-Class experience, but it still carries the model’s high price and rugged character. It includes the standard safety suite and luxury cabin features, yet it remains a costly way to get into the lineup.
• Premium/top trim: The AMG G63 is the performance-focused choice, with much more power and a higher price. It makes sense if you want the most dramatic version of the G-Class and are willing to pay for it.

The standard safety package is broad, but the lane-keep assist can be intrusive.

What is the 2020 Mercedes-Benz G-Class's resale value?

The current average of $122,517 sits slightly below last year's $126,144.

That price movement suggests the market has eased a bit, which can help you as a buyer today.

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.

It comes with 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 the windows, and adjusts the front-passenger seat in a crash scenario, plus Pre Safe Sound to help limit hearing damage. The main caveat is the lane-keep assist, which can react too aggressively and unexpectedly.

Should I buy a 2020 Mercedes-Benz G-Class or consider a different year?

• It offers a distinctive, upscale cabin with strong off-road credibility.

Consider the 2021 if:
