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

Prices have softened 2.45% compared to this time last year, making it a favorable time to shop this model year.

There are 798 listings available, which gives you a meaningful amount of inventory to compare.

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 luxurious feel, strong performance, and distinctive design, and they also like the visibility it provides. The trade-offs are the steep price and limited rear seating space. That lines up with the vehicle’s overall mission: you’re buying a five-passenger luxury body-on-frame SUV that prioritizes presence, capability, and character over everyday practicality. With 34.3% of listings marked as good or great deals, the market still 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 feedback points to a vehicle that feels luxurious and impressive, and the summary also emphasizes its performance and design in a positive way. The expert evaluation adds that the G-Class is a very capable, impressive, fun-to-drive vehicle, and Mercedes includes two years or 20,000 miles of Star Service covering two factory-scheduled maintenance visits. For used buyers, the main long-term risk is less about basic dependability and more about high ownership costs if you need repairs, options, or maintenance outside the included service window.

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 title percentage does not replace a proper inspection. Focus on body condition, interior wear, and evidence of hard use, since this is a vehicle that can attract buyers who use it for image as much as capability. It also makes sense to confirm that the equipment you want is actually present, because this model can be heavily optioned.

Key things to evaluate:

• Trim level: The G550 is the more accessible choice, while the G63 sits higher in the lineup with more power and more expensive positioning. The G-Class also offers extensive customization through the G Manufaktur Program, so equipment can vary widely from one example to another.
• 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 Dynamic Select driving programs, including 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 and make sure you’re comfortable with how it intervenes.
• Infotainment: The cabin uses a 12.3-inch widescreen infotainment display, with a matching 12.3-inch virtual instrument panel. Apple CarPlay and Android Auto are standard, and Mercedes me connect services are included for three years. 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 and Mercedes-AMG G63.

Here's the short version:

• G550: This is the trim that best captures the G-Class experience without pushing all the way into the highest price tier. You still get the twin-turbo V8, permanent four-wheel drive, the rugged body-on-frame setup, and the core luxury and tech features that define the model. If you want the most balanced entry point, this is the one to target.
• Mercedes-AMG G63: This is the more powerful, more expensive choice, with 577 horsepower and 627 pound-feet of torque. It suits you if you want the most dramatic performance and the most over-the-top version of the G-Class formula.

Standard safety equipment is generous on the G550, including active lane-keeping assist, active brake assist, active distance assist distronic, blind-spot monitoring, and more.

Is now a good time to buy a used 2021 Mercedes-Benz G-Class?

This is a moderate market for selective buyers, so it makes sense to compare listings carefully and move quickly on the right one.

• Deal availability: 34.3% of listings are priced as good or great deals.
• Inventory: There are 798 listings available.
• Price trend: Prices have softened 2.45% compared with last year.
• Clean inventory: 83.5% of listings are accident-free.

If you find a listing below $136,444, 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 $136,444 sits slightly below last year's $139,866.

That softer pricing suggests the market has become a bit more favorable for buyers, which can also mean future sellers may need to price competitively to stand out. Even so, the G-Class remains a distinctive luxury SUV with strong demand from shoppers who want its look and capability. Because the model has a clear identity and a loyal audience, 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 driver-assistance 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 understand how it behaves 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:

• 34.3% 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 2.45% compared with last year.
• Owners rate it 5/5 — a strong satisfaction signal.
• It keeps the iconic boxy look while pairing it with a luxury interior and more sophisticated powertrain and technology.

Consider the 2020 if:

• At $121,199, the 2020 costs less than the current year's $136,444 average.
• It blends ruggedness and luxury in a way few SUVs can match.

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