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

Prices have softened 6.96% compared to this time last year, making it a favourable time to shop this model year.

There are 55 listings available, which suggests a limited but active supply.

Is the 2021 Mercedes-Benz G-Class a good car?

Yes — owners rate it 5/5, and that lines up with the strong praise for its performance, visibility, and design. The review feedback also points to its luxury feel and impressive presence, while noting that the rear seating space is limited and the price is steep. For you, that means this is a strong fit if you want a distinctive luxury SUV with serious road presence and capability. With 23.6% of listings marked as good or great deals, there is some room to shop carefully.

Is the 2021 Mercedes-Benz G-Class reliable?

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

The review summary points to a vehicle that owners see as dependable and trouble-free in the context of long-term ownership, especially when judged against its luxury and performance mission. That said, used buyers should still expect higher ownership risk than with a mainstream SUV because this is an expensive, specialised vehicle.

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

This looks like a moderate, selective buyer’s market, so you can shop patiently and still find worthwhile opportunities.

• Deal availability: 23.6% of listings are priced as good or great deals.
• Inventory: There are 55 listings available.
• Price trend: Prices have softened 6.96% compared with last year.

If you find a listing below $178,931 CAD, 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 $182,932 CAD sits slightly below last year's $196,624 CAD.

That softer pricing can work in your favour if you buy now, but it also means a future seller may have less room for appreciation than in a stronger market. Even so, the G-Class remains a highly recognisable luxury SUV, which helps support demand. Its limited supply and strong enthusiast appeal can also help it hold attention better than many other used 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.

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:

• 23.6% of listings are priced as good or great deals.
• Price trend: Prices have softened 6.96% compared with last year.
• Owners rate it 5/5 — a strong satisfaction signal.

Consider the 2020 if:

• At $170,885 CAD, the 2020 costs less than the current year's $182,932 CAD average.
• It delivers a distinctive rugged-luxury character with true off-road capability.

The bottom line: Choose the 2021 if you want the newer-year pricing context and are focused on owner satisfaction and current market softness. If your priority is saving money upfront, the 2020 is the better value path, especially if you can find one with the features and condition you want.
