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

Prices have softened 2.49% compared to this time last year, making it a favorable time to shop this model year.

There are 792 listings available, which gives you a meaningful pool to compare before you commit.

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

Yes — it earns a 5/5 from owners and a 7.83/10 expert rating. The model scores 9/10 across Look and feel and Performance.

Owners consistently praise its luxury feel, strong performance, visibility, and distinctive design. The G-Class also stands out for its rugged, like-nothing-else presence and its powerful engine, which help it feel special rather than merely expensive.

The trade-offs are clear: expert testing calls out poor handling and limited cargo space, and owner feedback notes that the price can be steep and rear seating space is limited. If you want a five-passenger luxury SUV with serious character and off-road-ready hardware, this year’s G-Class fits that brief well.

Good and great deals make up 32.7% of listings, so you still have room to shop selectively.

Is the 2021 Mercedes-Benz G-Class reliable?

Owners rate it 5/5, a strong signal of long-term satisfaction. Owner feedback also points to a luxurious, impressive vehicle that many people find dependable in daily use, with praise centered on performance, visibility, and design.

The expert evaluation reinforces that impression by describing it as a capable, impressive, fun-to-drive vehicle with sophisticated mechanicals and technology. Mercedes also includes two years or 20,000 miles of Star Service covering two factory-scheduled maintenance visits, which helps reduce early ownership friction.

For used buyers, the main long-term risk is less about basic durability and more about expensive upkeep if the vehicle has been neglected or heavily optioned.

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

Accident-free inventory is solid at 83.5% — always verify the vehicle history report.

You should still check the history report carefully, because a clean listing percentage does not replace documentation. Prioritize a pre-purchase inspection that focuses on suspension, brakes, electronics, and signs of hard use, since this is a heavy, high-performance luxury SUV. Pay close attention to condition, because repair costs can rise quickly on a vehicle positioned this far upmarket.

Key things to evaluate:

• Trim level: The G550 is the lower-priced entry point, while the G63 adds more power and a higher starting price. The base model already brings the rugged exterior, luxury interior, and standard all-wheel drive, so you should decide whether the extra performance and opulence of the higher trim are worth the jump.
• Powertrain: The G550 uses a twin-turbocharged 4.0-liter V8 with 416 horsepower and 450 pound-feet of torque, 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 make sure you understand how it behaves before relying on it.
• Infotainment: You get a 12.3-inch widescreen infotainment display, a matching 12.3-inch virtual instrument panel, Bluetooth hands-free and streaming audio, Apple CarPlay, Android Auto, WiFi, and Mercedes me connect services.
• 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 and Mercedes-AMG G63.

Here's the short version:

• G550: This is the best-value choice if you want the core G-Class experience without paying for the AMG upgrade. You still get the iconic design, standard all-wheel drive, strong V8 power, and the full luxury-and-tech personality that defines the model.
• Mercedes-AMG G63: Choose this if you want the most powerful and most extravagant version of the G-Class. It turns the formula up with more horsepower, more torque, and a more over-the-top luxury presentation.

Safety equipment is broadly standard on the G550, including the driver-assistance suite listed above.

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: 32.7% of listings are priced as good or great deals.
• Inventory: There are 792 listings available.
• Price trend: Prices have softened 2.49% compared with last year.
• Clean inventory: 83.5% of listings are accident-free.

If you find a listing below $137,470, 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 $137,485 sits slightly below last year's $141,003.

That decline suggests the market has eased a bit, which can help you buy more confidently now than you could a year ago. For a future seller, it also means you should expect value to depend heavily on condition, mileage, and how well the vehicle has been maintained.

Because this model has a strong enthusiast following and a distinctive identity, well-kept examples should continue to attract attention. 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?

The 2021 Mercedes-Benz G-Class has not been rated for crash-worthiness or safety by the Insurance Institute for Highway Safety or the National Highway Traffic Safety Administration.

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 lane-keeping system is the main caveat, since it can intervene abruptly and may feel distracting if you are not expecting 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:

• 32.7% of listings are priced as good or great deals.
• Accident-free inventory is solid at 83.5% — always verify the vehicle history report.
• Price trend: Prices have softened 2.49% compared with last year.
• Owners rate it 5/5 — a strong satisfaction signal.
• It combines the classic boxy look with a luxury interior and sophisticated powertrain.

Consider the 2020 if:

• At $121,975, the 2020 costs less than the current year's $137,485 average.
• It blends ruggedness and luxury while keeping much of the old G-Wagen character.

The bottom line: If you want the strongest mix of current-market availability, owner satisfaction, and the model’s signature personality, the 2021 is the better default choice. If your priority is spending less up front, the 2020 is the more budget-friendly path and still delivers the core G-Class appeal.
