How much does the 2021 Mercedes-Benz G-Class cost?

Prices have softened 1.86% compared to this time last year, making it a favorable time to shop this model year.

With 804 listings available, you have a meaningful amount of inventory to compare across trims and conditions.

If you find a listing below $137,897.66, that's toward the low end of the year-round range and worth acting on quickly.

Is the 2021 Mercedes-Benz G-Class a good car?

Yes — owners rate it 5/5, and the expert rating is 7.83/10. The model scores 9/10 across Look and feel and Performance.

Owners consistently praise its performance, visibility, and design, which lines up with the G-Class’s distinctive luxury-and-capability appeal. The trade-offs are just as clear: the price is steep, rear seating space is limited, and the ride is not for shoppers who want a conventional SUV experience. For you, that means the G-Class makes the most sense if you want a five-passenger body-on-frame SUV with standard all-wheel drive and a strong personality rather than a value play. Good and great deals account for 33.1% of listings, which gives you some room to shop selectively.

Is the 2021 Mercedes-Benz G-Class reliable?

Owners rate it 5/5, a strong signal of long-term satisfaction.

The owner summary points to a vehicle that feels luxurious, impressive, and dependable, with the kind of performance and design that owners tend to keep appreciating over time. The expert evaluation also describes it as a capable, fun-to-drive vehicle, which reinforces the sense that it is built to deliver a memorable ownership experience. Mercedes-Benz includes two years or 20,000 miles of Star Service covering two factory-scheduled maintenance visits, which helps early ownership costs. For used buyers, the main long-term risk is that a complex, expensive SUV can become costly if prior maintenance or condition has been neglected.

What should I look for when buying a used 2021 Mercedes-Benz G-Class?

Accident-free inventory is solid at 84.7% — always verify the vehicle history report.

You should still check the history report carefully, because a clean listing percentage does not replace a proper records review. Prioritize a pre-purchase inspection that focuses on body condition, electronics, and signs of hard use, since this is a high-priced SUV that may have seen demanding ownership. Pay close attention to whether the vehicle’s equipment and condition match the asking price, especially if it has been customized.

Key things to evaluate:

• Trim level: The G-Class is offered as the G550 and the G63. The G550 is the more approachable choice, while the G63 adds more power and more luxury-oriented equipment.
• Powertrain: The G550 uses a twin-turbocharged 4.0-liter V8 with 416 horsepower and 450 pound-feet of torque, paired with a nine-speed automatic transmission and permanent four-wheel drive. It is quick for its size, with a 5.6-second zero-to-60 time, but fuel economy is poor.
• Safety package: Standard equipment includes a rearview camera, Pre-Safe, traffic-sign assist, attention assist, active lane-keeping assist, active brake assist, active distance assist distronic, active parking assist, and blind-spot monitoring. The lane-keeping system can feel abrupt, so you should test it carefully.
• Infotainment: The cabin features twin 12.3-inch displays, Bluetooth hands-free and streaming audio, Apple CarPlay, Android Auto, WiFi, and Mercedes me connect services. Wireless device charging is not provided.
• Fuel efficiency: The G550 is rated at 13 mpg city, 19 mpg highway, and 18 mpg combined. The G63 returns 13 mpg city, 16 mpg highway, and 14 mpg combined.

Which 2021 Mercedes-Benz G-Class trim should I buy?

The 2021 Mercedes-Benz G-Class is offered in 2 trim levels: G550, G63.

Here's the short version:

• Base trim: The G550 gives you the core G-Class experience with standard all-wheel drive, strong performance, and the full suite of standard driver-assistance features. It is still expensive, and you should expect limited cargo space and poor fuel economy.
• Premium/top trim: The G63 is the more powerful and more lavish choice, with a higher-output V8 and more over-the-top luxury. It makes sense if you want the most dramatic version of the G-Class and are comfortable paying for it.

The standard safety package is broad, but the lane-keeping system deserves a careful test drive before you commit.

Is now a good time to buy a used 2021 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: 33.1% of listings are priced as good or great deals.
• Inventory: There are 804 listings available.
• Price trend: Prices have softened 1.86% compared with last year.
• Clean inventory: 84.7% of listings are accident-free.

If you find a listing below $137,897.66, that's toward the low end of the year-round range and worth acting on quickly.

What is the 2021 Mercedes-Benz G-Class's resale value?

The current average of $139,270 sits slightly below last year's $141,914.

That kind of softening suggests the market is giving buyers a bit more leverage than it was a year ago. If you buy well now, you may have a better chance of limiting depreciation compared with paying closer to the top of the range. Strong demand for distinctive, highly rated vehicles can help support future resale, especially when the model has a clear identity and broad appeal among enthusiasts.

Vehicles with strong owner satisfaction ratings, like this model year's 5/5, tend to retain buyer demand, which supports resale value over time.

Is the 2021 Mercedes-Benz G-Class safe?

It earns an 8/10 safety score from our experts.

Standard safety equipment includes a rearview camera, Pre-Safe, traffic-sign assist, attention assist, active lane-keeping assist, active brake assist, active distance assist distronic, active parking assist, and blind-spot monitoring. The G-Class’s size and body-on-frame construction can offer some advantages in certain crashes, but its mass also means you need to be especially mindful of how it affects others around you. The lane-keeping assist system can feel abrupt, so that is a feature you should understand before relying on it.

Should I buy a 2021 Mercedes-Benz G-Class or consider a different year?

If you're weighing the 2021 against nearby model years, here's how to think about it:

Choose the 2021 if:

• 33.1% of listings are priced as good or great deals.
• Accident-free inventory is solid at 84.7% — always verify the vehicle history report.
• Price trend: Prices have softened 1.86% compared with last year.
• Owners rate it 5/5 — a strong satisfaction signal.
• The 2021 G-Class combines iconic styling with strong performance and standard all-wheel drive.

Consider the 2020 if:

• At $122,517, the 2020 costs less than the current year's $139,270 average.
• It offers a distinctive, rugged luxury feel with true off-road character.

The bottom line: If you want the stronger current-market balance of inventory, satisfaction, and price movement, the 2021 is the better target. If your priority is spending less up front, the 2020 is the more budget-conscious path and still delivers the G-Class personality you’re shopping for.
