What is the 2020 GMC Sierra 1500's resale value?

The current average of $38,301 CAD sits slightly below last year's $43,809 CAD.

That softer pricing can help you buy more truck for the money today, but it also means future resale may depend more heavily on condition, trim, and equipment. If you keep the truck well maintained and choose a desirable configuration, you’re more likely to protect value when it’s time to sell. The current market also suggests buyers are still interested, which helps support pricing stability.

Vehicles with solid owner satisfaction ratings, like this model year's 4.28/5, tend to retain buyer demand, which supports resale value over time.

Should I buy a 2020 GMC Sierra 1500 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:

• 32.1% of listings are priced as good or great deals.
• Price trend: Prices have softened 12.57% compared with last year.
• Owners rate it 4.28/5 — a solid satisfaction signal.

Consider the 2021 if:

• At $39,859 CAD, the 2021 costs more than the current year's $38,301 CAD average.
• It adds a carbon-fibre composite cargo bed for a more distinctive pickup setup.

The bottom line:
You should start with the 2020 if you want the better value play, especially since pricing has eased and inventory is healthy. If you’re willing to spend more for a slightly newer truck with a more distinctive cargo-bed option, the 2021 is the better secondary path.
