Is the 2020 Mercedes-Benz G-Class a good car?

The 2020 Mercedes-Benz G-Class earns an expert rating of 7.17/10.

The standout strength is Look and feel at 9/10.

You get a vehicle that blends rugged, old-school character with the luxury and technology you expect from Mercedes-Benz, and that unusual mix is a big part of its appeal. It also remains one of the last SUVs with true off-road capability, while still feeling distinctive rather than conventional.

There are 34.6% of listings priced as good or great deals, which gives you some room to shop selectively.

Is the 2020 Mercedes-Benz G-Class reliable?

The 2020 Mercedes-Benz G-Class is built around a rugged, body-on-frame design and serious off-road hardware, which supports its tough reputation. The expert drive notes also point to generally strong driver-assistance performance, with lane-keep assist as the main concern because it can react too aggressively.

Its powertrain is straightforward and proven in concept, with a twin-turbocharged V8 and standard four-wheel drive paired with a nine-speed automatic transmission. The cabin and feature set are also very much in line with a high-end Mercedes, which reinforces the sense that this is a premium product rather than a stripped-down off-roader.

For used buyers, the main long-term risk is that you are shopping for a complex, expensive SUV that can be costly to own if maintenance or repairs stack up.

What should I look for when buying a used 2020 Mercedes-Benz G-Class?

Key things to evaluate:

• Trim level: The cabin is loaded with standard luxury touches such as leather upholstery, heated front and rear seats, a heated steering wheel, three-zone automatic climate control, and 64-colour ambient lighting, while the AMG version adds a more aggressive presence with a standard front push bar.
• Powertrain: The G550 uses a 4.0-litre twin-turbocharged V8 with 416 horsepower and 450 pound-feet of torque, while the AMG G63 uses a higher-output twin-turbo V8 with 577 horsepower and 627 pound-feet of torque; both use four-wheel drive and a nine-speed automatic transmission.
• Safety package: Standard driver assistance includes adaptive cruise control with stop-and-go, automatic emergency brake assist, lane-keep assist, blind-spot monitoring, parking assist, and a driver-attention monitor, with Pre Safe adding seatbelt tightening, window closing, and front-passenger seat adjustment.
• Infotainment: You get a 12.3-inch infotainment display, a second 12.3-inch digital instrument cluster, Apple CarPlay/Android Auto, Bluetooth, SiriusXM satellite radio, and a 15-speaker, 590-watt Burmester audio system.
• Fuel efficiency: Natural Resources Canada rates the G550 at 13.6 L/100 km in the city, 12.4 on the highway, and 13.1 combined; the AMG G63 is rated at 18.6 city, 15.5 highway, and 17.2 combined.

Which 2020 Mercedes-Benz G-Class trim should I buy?

The 2020 Mercedes-Benz G-Class is offered in 2 trim levels: G550 and AMG G63.

Here's the short version:

• G550: This is the better-value choice if you want the core G-Class experience, with the twin-turbo V8, standard four-wheel drive, serious off-road hardware, and the full luxury cabin without stepping up to the much pricier AMG model.
• AMG G63: Choose this if you want the most powerful and most dramatic version, with substantially more output and the performance-focused character that comes with the AMG badge.

The safety package is strong across the range, with standard adaptive cruise control, automatic emergency brake assist, lane-keep assist, blind-spot monitoring, parking assist, and a driver-attention monitor.

Is now a good time to buy a used 2020 Mercedes-Benz G-Class?

This is a moderate market for selective buyers, so it makes sense to compare listings carefully and move quickly when you find a strong example.

• Deal availability: 34.6% of listings are priced as good or great deals.
• Inventory: There are 52 listings available.
• Price trend: Prices have softened 3.14% compared with last year.

If you find a listing below $156,234 CAD, that's toward the low end of the year-round range and worth acting on quickly.

What is the 2020 Mercedes-Benz G-Class's resale value?

The current average of $172,610 CAD sits slightly below last year's $178,205 CAD.

That softer pricing suggests the market has eased a bit, which can help you as a buyer today. For a future seller, it means you should not expect this model year to command the same average pricing it did a year ago. If you buy well now, you may have a better chance of limiting depreciation pressure later, but this is still a high-priced SUV with a narrow buyer pool.

Is the 2020 Mercedes-Benz G-Class safe?

The 2020 G-Class hasn’t received crash-test ratings from the Insurance Institute for Highway Safety (IIHS) or National Highway Traffic Safety Administration (NHTSA).

It earns a 7/10 safety score from our experts.

The G-Class gets a long list of safety features, including adaptive cruise control with stop-and-go, automatic emergency brake assist, lane-keep assist, blind-spot monitoring, parking assist, and a driver-attention monitor. Mercedes’ Pre Safe system also tightens the seatbelts, closes the windows, and adjusts the front-passenger seat to help protect occupants if a collision is unavoidable.

One caveat is that lane-keep assist can be overly aggressive and has been known to make false corrections.

Should I buy a 2020 Mercedes-Benz G-Class or consider a different year?

If you're weighing the 2020 against nearby model years, here's how to think about it:

Choose the 2020 if:

• 34.6% of listings are priced as good or great deals.
• Price trend: Prices have softened 3.14% compared with last year.
• The 2020 stands out for its blend of ruggedness, luxury, and true off-road capability.

The bottom line: The 2020 G-Class makes the most sense if you want the classic boxy look, serious off-road hardware, and a luxury cabin in one package. If you are price-sensitive, the softer market and decent share of good deals make this a reasonable year to target, but you should still compare carefully because inventory is limited and examples vary widely in equipment.
