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

Prices have softened 3.61% compared to this time last year, making it a favorable time to shop this model year.

There are 727 listings available, which gives you a meaningful pool to compare prices and equipment.

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 7.8/10 expert rating. The model scores 9/10 across Look and feel and Performance.

Owners consistently praise its luxurious feel, impressive performance, visibility, and distinctive design. The G-Class also fits buyers who want a five-passenger luxury body-on-frame SUV with a rugged, off-road-ready personality and a strong sense of presence.

The trade-offs are clear: poor handling and poor fuel economy. It also leans more toward exclusivity and capability than everyday practicality, especially if you care about cargo space.

Good and great deals account for 31.9% of listings, so you can still find 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.

Owner feedback points to a vehicle that feels luxurious, impressive, and dependable enough to inspire confidence over time. The expert review also emphasizes its capable, fun-to-drive character and its robust, body-on-frame construction, which supports the sense that it is built for serious use.

Mercedes 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 upkeep can be expensive, so service history matters.

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

Accident-free inventory is solid at 82.7% — always verify the vehicle history report.

You should still check each listing carefully, because a clean history percentage does not guarantee a perfect individual vehicle. Prioritize a pre-purchase inspection, confirm maintenance records, and pay close attention to wear on the interior, electronics, and suspension. Since this SUV is expensive to buy and maintain, condition matters more than mileage alone.

Key things to evaluate:

• Trim level: The G-Class lineup includes the G550 and the Mercedes-AMG G63. The G550 is the more accessible choice, while the AMG model adds more power and more opulence.
• 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, blind-spot monitoring, and more. The lane-keeping system can feel abrupt, so make sure you understand how it behaves before relying on it.
• Infotainment: The cabin features twin 12.3-inch displays, a 12.3-inch infotainment screen, Apple CarPlay, Android Auto, Bluetooth, WiFi, and Mercedes me connect services. Wireless device charging is not provided.
• Fuel efficiency: EPA fuel economy ratings for the G550 are 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 that best fits most shoppers because it delivers the core G-Class experience: the boxy design, luxury cabin, standard all-wheel drive, strong V8 power, and the full suite of standard safety and tech features. It is the better-value choice if you want the G-Wagen character without stretching to the top-end AMG model.
• Mercedes-AMG G63: Choose this if you want the most powerful, most extravagant version of the G-Class and are willing to pay for it. It builds on the same basic formula but turns the luxury and performance up further.

The standard safety package is broad, but the lane-keeping system can be intrusive, so test it carefully.

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 patient.

• Deal availability: 31.9% of listings are priced as good or great deals.
• Inventory: There are 727 listings available.
• Price trend: Prices have softened 3.61% compared with last year.
• Clean inventory: 82.7% of listings are accident-free.

If you find a listing below $135,217, 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 $135,217 sits slightly below last year's $140,280.

That softer pricing suggests the market has cooled a bit, which can help you buy more carefully now. For a future seller, the current trend means resale value may be steadier if the vehicle remains well kept and properly documented. Strong condition and a clean history should matter a lot in preserving demand.

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.

Mercedes 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, blind-spot monitoring, and more. The lane-keeping system can feel abrupt, so you should understand its behavior before depending 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:

• 31.9% of listings are priced as good or great deals.
• Accident-free inventory is solid at 82.7% — always verify the vehicle history report.
• Price trend: Prices have softened 3.61% compared with last year.
• Owners rate it 5/5 — a strong satisfaction signal.
• The 2021 model pairs its rugged shape with a luxury interior and sophisticated powertrain.

Consider the 2020 if:

• At $118,065, the 2020 costs less than the current year's $135,217 average.
• It keeps the classic G-Wagen look while adding luxury and true off-road capability.

The bottom line: Choose the 2021 if you want the current-year market mix of strong satisfaction, decent deal availability, and a distinctive luxury SUV experience. If your priority is spending less up front, the 2020 is the more budget-friendly path and still delivers the core G-Class character.
