Used 2021 Mercedes-Benz G-Class for Sale nearNew York, NY

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

Prices have softened 2.30% compared to this time last year, making it a favorable time to shop this model year.

There are 821 listings available, which gives you a meaningful amount of inventory to compare.

If you find a listing below $137,892.39, 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 they also describe it as luxurious and impressive. The trade-offs are clear: the ride comes with a steep price tag, limited rear seating space, poor handling, poor fuel economy, and limited cargo space. In use-case terms, it fits you best if you want a five-passenger luxury SUV that stands out from mainstream options and you value character as much as capability.

Only 28.9% of listings are priced as good or great deals, so the market still rewards careful shopping.

Is the 2021 Mercedes-Benz G-Class reliable?

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

Owners describe it as luxurious and impressive, and the review summary points to the kind of performance and design that can make the vehicle feel dependable and confidence-inspiring over time. The expert evaluation also emphasizes its capable, fun-to-drive nature and its sophisticated mechanicals, which supports the impression of a well-engineered SUV. Mercedes-Benz includes two factory-scheduled maintenance services over two years or 20,000 miles through Star Service, which can help early ownership costs feel more predictable.

For used buyers, the main long-term risk is that a vehicle this complex and expensive can become costly if prior maintenance was skipped or deferred.

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

Accident-free inventory is solid at 85.1% — always verify the vehicle history report.

You should still check the vehicle history report carefully, because a clean listing percentage does not replace documentation. Prioritize a pre-purchase inspection that focuses on wear, maintenance records, and any signs of heavy use. Given the G-Class’s size, price, and capability, condition matters a lot more than mileage alone.

Key things to evaluate:

• Trim level: The G550 is the more accessible choice, while the G63 adds more power and a higher starting price. The G550 already brings the rugged look, luxury interior, and standard all-wheel drive that define the model, so you should focus on whether the extra performance and opulence of the AMG version are worth the jump.
• 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 offers 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 understand how it behaves before relying on it.
• Infotainment: The cabin features 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. 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, G63.

Here's the short version:

• G550: This is the better-value choice if you want the core G-Class experience without stretching to the AMG price. You still get the iconic boxy design, luxury interior, standard all-wheel drive, strong V8 power, and the full suite of standard driver-assistance features. It is the trim that best balances capability, character, and cost.
• 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 feel, but it also pushes the price much higher.

The standard safety package is broad on the G550, but you should still test the lane-keeping behavior before you buy.

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

This is a moderate, selective buyer’s market, so you should shop carefully and compare listings.

• Deal availability: 28.9% of listings are priced as good or great deals.
• Inventory: There are 821 listings available.
• Price trend: Prices have softened 2.30% compared with last year.
• Clean inventory: 85.1% of listings are accident-free.

If you find a listing below $137,892.39, 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 $138,381 sits slightly below last year's $141,636.

That softer pricing suggests the market has cooled a bit, which can help you buy more selectively today. For a future seller, it also means resale value may depend heavily on condition, mileage, and how well the vehicle has been maintained. Because this model has strong enthusiast appeal and a distinctive identity, clean 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?

It earns a 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 in normal driving. You should test that system carefully and make sure you are comfortable with how it behaves.

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:

• 28.9% of listings are priced as good or great deals.
• Accident-free inventory is solid at 85.1% — always verify the vehicle history report.
• Price trend: Prices have softened 2.30% compared with last year.
• Owners rate it 5/5 — a strong satisfaction signal.
• The 2021 keeps the G-Class’s iconic boxy design while pairing it with a luxury interior and sophisticated powertrain.

Consider the 2020 if:

• At $121,532, the 2020 costs less than the current year's $138,381 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 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 G-Class personality you’re shopping for.
