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

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

• Deal availability: 31.5% of listings are priced as good or great deals.
• Inventory: There are 54 listings available.
• Price trend: Prices have softened 2.92% 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 $181,439 CAD sits slightly below last year's $186,891 CAD.

That softer pricing can help you buy more strategically now, but it also suggests future sellers may face some pressure if the market stays similar. If you plan to resell later, the current trend shows that values are not climbing aggressively, so condition and mileage will matter even more. Strong owner satisfaction can still support demand when it is time to sell.

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:

• 31.5% of listings are priced as good or great deals.
• Price trend: Prices have softened 2.92% compared with last year.
• Owners rate it 5/5 — a strong satisfaction signal.

Consider the 2020 if:

• At $173,107 CAD, the 2020 costs less than the current year's $181,439 CAD average.
• It delivers a rugged, old-school character with strong off-road appeal.

The bottom line: Choose the 2021 if you want the stronger current-market balance of owner satisfaction, pricing, and available inventory. If your priority is saving money upfront, the 2020 is the better value path, especially if you like the G-Class’s distinctive rugged personality and can live with the older-year pricing advantage.
