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

Prices have softened 2.29% compared to this time last year, making it a favorable time to shop this model year.

With 808 listings available, you have a meaningful amount of inventory to compare before you commit.

If you find a listing below $137,736.87, 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 — the 2021 Mercedes-Benz G-Class earns a 5/5 user rating and a 7.83/10 expert rating. The model scores 9/10 across Look and feel and Performance.

Owners consistently praise its performance, visibility, and design, and the G-Class also stands out for being unlike almost anything else on the road. The trade-offs are clear: poor handling and limited cargo space show up in the expert review, and the price is steep for many shoppers. If you want a five-passenger, body-on-frame luxury SUV with standard all-wheel drive and a strong personality, this year fits that brief well. With 30.8% of listings marked as good or great deals, there is still 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 feedback points to a luxurious, impressive vehicle that many people find dependable in daily use, with praise centered on performance and design. The expert review also emphasizes that it is a very capable, impressive, fun-to-drive vehicle, which supports the idea that it can deliver a satisfying ownership experience over time. Mercedes-Benz also includes two factory-scheduled maintenance services through its Star Service plan, which can help with early ownership costs. For used buyers, the main long-term risk is that a complex, high-priced SUV can become expensive to keep in top shape if prior maintenance was neglected.

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

Accident-free inventory is solid at 84.2% — always verify the vehicle history report.

You should still check the history report carefully, because a clean listing percentage does not replace a proper paper trail. Prioritize a pre-purchase inspection that focuses on suspension, brakes, electronics, and signs of hard use. Pay close attention to condition, since this is a high-cost SUV where deferred maintenance can add up quickly.

Key things to evaluate:

• Trim level: The G-Class is offered as the G550 and the Mercedes-AMG G63. The G550 is the more approachable choice, while the G63 brings a higher starting price and more extreme performance and luxury.
• 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 also includes driving programs such as G-mode for more assertive off-roading.
• 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, Apple CarPlay, Android Auto, Bluetooth, WiFi, and Mercedes me connect services. The system uses Mercedes-Benz COMAND, and wireless device charging is not provided.
• Fuel efficiency: The G550 is rated at 13 mpg city, 19 mpg highway, and 18 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, Mercedes-AMG G63.

Here's the short version:

• G550: This is the trim most shoppers should start with because it delivers the core G-Class experience: the iconic design, strong V8 power, standard all-wheel drive, and the luxury-tech cabin. It is the better-value choice if you want the character without pushing all the way to the top of the price range.
• Mercedes-AMG G63: Choose this if you want the most powerful and most expensive version, along with the extra performance and more over-the-top luxury feel that come with the AMG badge.

The safety package is broad on the G550, but the lane-keeping system deserves a careful test drive before you buy.

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 with some leverage if you stay disciplined.

• Deal availability: 30.8% of listings are priced as good or great deals.
• Inventory: There are 808 listings available.
• Price trend: Prices have softened 2.29% compared with last year.
• Clean inventory: 84.2% of listings are accident-free.

If you find a listing below $137,736.87, 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 $137,695 sits slightly below last year's $140,920.

That softer pricing suggests the market has eased a bit, which can help you buy more carefully now. For a future seller, the current trend implies that resale value may remain supported, but not immune to broader price pressure. The G-Class still has strong appeal because it is distinctive, desirable, and highly recognizable, which helps keep buyer interest alive.

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.

Mercedes-Benz equips the G550 with 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. That is a strong standard safety list for a luxury SUV, but the lane-keeping system can feel abrupt and should be tested before you buy. The vehicle has not been rated for crash-worthiness or safety by either IIHS or NHTSA, so you should lean more heavily on the standard equipment and your own inspection.

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:

• 30.8% of listings are priced as good or great deals.
• Accident-free inventory is solid at 84.2% — always verify the vehicle history report.
• Price trend: Prices have softened 2.29% compared with last year.
• Owners rate it 5/5 — a strong satisfaction signal.
• The 2021 keeps the iconic boxy look while pairing it with a luxury interior and sophisticated powertrain.

Consider the 2020 if:

• At $121,485, the 2020 costs less than the current year's $137,695 average.
• It blends serious ruggedness with luxury and technology while preserving old-school G-Class character.

The bottom line: If you want the strongest mix of current-market availability, owner satisfaction, and the updated G-Class formula, the 2021 is the better target. If your priority is spending less up front and you still want the classic G-Class personality, the 2020 is the more price-conscious path.
