What should I look for when buying a used 2021 GMC Yukon?

Key things to evaluate:

• Trim level: The Yukon comes in SLE, SLT, AT4, and Denali trims. The base SLE is the most stripped-down version, while SLT adds more convenience and safety equipment, and Denali brings the most upscale cabin and the most premium feel.
• Powertrain: You can get a standard 5.3-litre V8, an available 3.0-litre turbo-diesel, or a 6.2-litre V8 that is standard only on Denali. The 6.2-litre engine delivers strong acceleration, while the diesel is the efficiency-minded choice.
• Safety package: The Yukon includes forward collision warning, daytime pedestrian detection, automatic emergency braking below 80 km/h, and automatic high-beam headlights. Starting with SLT, you also get blind-spot warning, rear cross-traffic warning, lane-departure warning, and lane-keeping assistance. Adaptive cruise control and enhanced automatic emergency braking are reserved for Denali.
• Infotainment: All 2021 Yukons get a 10.2-inch touchscreen with wireless Apple CarPlay, wireless Android Auto, and over-the-air updates. Higher trims add wireless charging, navigation, a 14-speaker Bose audio system, and rear-seat entertainment with dual 12.6-inch displays.
• Fuel efficiency: The 6.2-litre V8 with 4WD is rated at 16.8 L/100 km in the city, 12.4 on the highway, and 14.8 combined. The review also notes that fuel efficiency can worsen compared with the previous generation.

Which 2021 GMC Yukon trim should I buy?

The 2021 GMC Yukon is offered in 4 trim levels: SLE, SLT, AT4, and Denali.

Here's the short version:

• SLE: This is the entry point if you want the Yukon’s space, standard infotainment, and core safety tech without paying for extras you may not need. It makes sense if you want the most affordable way into the model.
• SLT: This is the best-value trim for many shoppers because it adds important safety equipment, including blind-spot warning, rear cross-traffic warning, lane-departure warning, and lane-keeping assistance. It’s the trim to target if you want a more complete daily driver.
• AT4: Choose this if you want the Yukon’s more adventurous side, since it adds off-road-focused hardware such as improved approach angle, skid plates, and all-terrain tires.
• Denali: This is the luxury pick, with the most upscale cabin, the 6.2-litre V8, and access to adaptive cruise control and enhanced automatic emergency braking. It suits you best if comfort and premium features matter most.

The safety package gets more complete as you move up the range, with Denali adding the most advanced driver-assistance features.

Is now a good time to buy a used 2021 GMC Yukon?

This is a moderate market for selective buyers, so it pays to compare listings carefully and move quickly on strong examples.

• Deal availability: 36.1% of listings are priced as good or great deals.
• Inventory: There are 72 listings available.
• Price trend: Prices have softened 19.10% compared with last year.

If you find a listing below $53,097 CAD, that's toward the low end of the year-round range and worth acting on quickly.

What is the 2021 GMC Yukon’s resale value?

The current average of $53,097 CAD sits slightly below last year's $65,637 CAD.

That price drop suggests the Yukon is currently in a softer part of its value cycle, which can be helpful if you’re buying now but less favourable if you’re planning to sell soon. For a future seller, the key takeaway is that resale value will depend heavily on how well the market continues to absorb full-size SUVs at this price point.

If demand stays steady, well-equipped examples should remain easier to move than poorly optioned or heavily worn ones. 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 GMC Yukon 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:

• 36.1% of listings are priced as good or great deals.
• Price trend: Prices have softened 19.10% compared with last year.
• Owners rate it 5/5 — a strong satisfaction signal.
• The 2021 brings a redesigned cabin, more space, and a major technology upgrade.

Consider the 2022 if:

• At $63,368 CAD, the 2022 costs more than the current year's $53,097 CAD average.
• It adds a standard 12-inch driver information centre and enhanced connectivity.

The bottom line: If you want the better value today, the 2021 is the smarter buy because prices are softer and inventory is available. If you’re willing to pay more for the newer model’s added connectivity and display upgrade, the 2022 is the cleaner step up.
