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

The 2020 Mercedes-Benz G-Class earns an 7.17/10 expert rating, and it stands out because it blends ruggedness and luxury in a way few SUVs can match. It has an anachronistic look and feel, but it also brings the luxury and technology features you’d expect from Mercedes, which makes it especially appealing if you want something distinctive rather than conventional.

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

That unusual mix is a big part of its appeal, especially if you want a vehicle with true off-road capability and a cabin that feels worthy of a six-figure SUV. With 29.4% of listings marked as good or great deals, there is at least some market flexibility if you shop carefully.

Is the 2020 Mercedes-Benz G-Class reliable?

The 2020 Mercedes-Benz G-Class is presented as a rugged, luxury-focused SUV with true off-road hardware and a long list of standard safety features. Its expert performance notes also point to a vehicle that feels remarkably precise on the road for something so tall and heavy, while still retaining serious off-road capability.

The performance content also highlights standard four-wheel drive, a nine-speed automatic transmission, low range, and front, centre, and rear locking differentials, which are the kinds of hardware that support dependable use in difficult conditions. The cost-effectiveness notes also make clear that this is not a value play, so long-term ownership risk for used buyers is less about bargain pricing and more about accepting high running costs and premium upkeep.

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

Key things to evaluate:

• Trim level: The cabin is the big differentiator here, with standard leather upholstery, heated front and rear seats, a heated steering wheel, three-zone automatic climate control, and 64-colour ambient lighting. The AMG G-Class model adds a standard front push bar, while available upgrades include Nappa leather, wood or carbon fibre trim, and massaging and rapid-heating front seats.
• 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 souped-up twin-turbo V8 with 577 hp and 627 lb-ft of torque. Four-wheel drive and a nine-speed automatic transmission are standard, and the G550 is the calmer, more practical choice if you do not need the extra AMG output.
• Safety package: Standard equipment 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. Mercedes’ Pre Safe system also tightens the seatbelts, closes windows, and adjusts the front-passenger seat, while Pre Safe Sound plays pink noise to help limit hearing damage.
• Infotainment: You get a 12.3-inch infotainment display, a second 12.3-inch digital instrument cluster, Apple CarPlay/Android Auto, Bluetooth, and SiriusXM satellite radio. The system uses a Comand controller rather than a touchscreen, and the interface can feel a bit slow and awkward to use.
• 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 G-Class experience without paying for the AMG’s extra power. It still gives you the full off-road hardware, the twin-turbo V8, and the luxury cabin features that define the model.
• AMG G63: Choose this if you want the most powerful and most expensive version, plus the more aggressive AMG character and the standard front push bar. It suits you best if performance and presence matter more than value.

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

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

This looks like a moderate market for selective buyers, so you should be able to shop with some leverage if you are patient.

• Deal availability: 29.4% of listings are priced as good or great deals.
• Inventory: There are 51 listings available.
• Price trend: Prices have softened 3.75% compared with last year.

If you find a listing below $156,232 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 $171,426 CAD sits slightly below last year's $178,104 CAD.

That softer pricing suggests the market has eased a bit for buyers, which can help if you are shopping now. For a future seller, it means you may not recover as much as you would have a year ago unless your vehicle is especially well equipped or exceptionally clean.

Because the G-Class sits in a niche luxury segment, resale will likely continue to depend heavily on condition, mileage, and specification. If you buy carefully and keep the SUV in strong shape, you should still have a desirable used vehicle to sell later.

Is the 2020 Mercedes-Benz G-Class safe?

The 2020 Mercedes-Benz 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.

It 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 windows, and adjusts the front-passenger seat to help keep occupants in place, and Pre Safe Sound plays pink noise designed to limit hearing damage.

One caveat is that lane-keep assist had a few false alarms and could react aggressively, which is worth keeping in mind if you plan to rely on it often.

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:

• 29.4% of listings are priced as good or great deals.
• Price trend: Prices have softened 3.75% compared with last year.
• It appeals to you because it keeps the distinctive old-school G-Class character while still delivering the luxury and tech features you expect from Mercedes.

The bottom line: The 2020 G-Class makes the most sense if you want the model’s unique blend of luxury, presence, and real off-road hardware. If you are price-sensitive, the softer market and decent inventory make this a reasonable year to target, but you should still focus on condition and equipment rather than chasing the cheapest example.
