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

Prices have softened 2.17% compared to this time last year, making it a favorable time to shop this model year.

There are 781 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 7.83/10 expert rating. The model scores 9/10 across Look and feel and Performance.

Owners consistently praise its performance, visibility, and design, and the review summary also points to a luxurious and impressive driving experience. In practical terms, that lines up with the G-Class’s distinctive use case: a five-passenger luxury body-on-frame SUV with serious presence and off-road-ready character.

The trade-offs are clear, though: poor handling and not much cargo space make it less appealing if you want an easy everyday hauler. Inventory also looks reasonably shopper-friendly, with 34.7% of listings marked as good or great deals.

Is the 2021 Mercedes-Benz G-Class reliable?

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

The owner feedback also points to a vehicle that feels reliable, dependable, and trouble-free in the ways shoppers care about most, especially for a long-term ownership experience. On the expert side, the G-Class is described as a capable, impressive vehicle with a powertrain and mechanical setup that support confidence over time.

Mercedes also includes two years or 20,000 miles of factory-scheduled maintenance coverage through Star Service, which helps reduce early ownership friction. For used buyers, the main long-term risk is cost: this is still an expensive SUV to buy, maintain, and keep in top condition.

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

Accident-free inventory is solid at 83.6% — always verify the vehicle history report.

You should still run a history report on any listing you like, because a clean market average does not guarantee a clean individual vehicle. Prioritize a pre-purchase inspection, especially if the SUV has been driven hard, modified, or used off pavement. Focus on condition, maintenance records, and signs of wear in the cabin and underbody.

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 G63 adds more power and more luxury, so the base model is the one most likely to leave you wanting if you expect the full flagship experience.
• 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 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 understand how it behaves before relying on it.
• Infotainment: The cabin features a 12.3-inch widescreen infotainment display, with a matching 12.3-inch virtual instrument panel. Apple CarPlay and Android Auto are standard, and the system includes Bluetooth, 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 classic G-Class experience without stepping all the way up to the AMG model. You still get the twin-turbo V8, permanent four-wheel drive, strong off-road hardware, and the full luxury presence that defines the nameplate.
• Mercedes-AMG G63: Choose this if you want the most power, the most dramatic performance, and the most over-the-top version of the G-Class. It is the pricier, more indulgent option, so it makes sense if you care more about maximum presence and acceleration than value.

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 rewards comparison shopping rather than impulse buying.

• Deal availability: 34.7% of listings are priced as good or great deals.
• Inventory: There are 781 listings available.
• Price trend: Prices have softened 2.17% compared with last year.
• Clean inventory: 83.6% of listings are accident-free.

If you find a listing below $137,366, 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 $137,396 sits slightly below last year's $140,438.

That tells you the market has eased a bit, which can help you buy more carefully now, but it also means future sellers may face some pressure if pricing softens further. Even so, the G-Class’s strong identity and loyal following help support demand better than many luxury SUVs.

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.

The G550 comes with a broad standard safety suite that 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. That gives you a lot of driver assistance right from the start.

One caveat is that the lane-keeping system can feel abrupt when it intervenes, so you should test it and understand its behavior before depending on it. The vehicle has not been rated for crash-worthiness or safety by IIHS or NHTSA.

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:

• 34.7% of listings are priced as good or great deals.
• Accident-free inventory is solid at 83.6% — always verify the vehicle history report.
• Price trend: Prices have softened 2.17% compared with last year.
• Owners rate it 5/5 — a strong satisfaction signal.
• It keeps the classic boxy G-Class look while pairing it with a luxury interior and sophisticated powertrain.

Consider the 2020 if:

• At $122,209, the 2020 costs less than the current year's $137,396 average.
• It blends ruggedness and luxury in a way few SUVs can match.

The bottom line: If you want the stronger current-market mix of inventory, pricing momentum, and owner satisfaction, the 2021 is the better primary pick. If your priority is spending less up front, the 2020 is the smarter value play, especially if you still want the G-Class character.
