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

The current average of $37,958 CAD sits slightly below last year's $43,942 CAD.

That softer pricing can help you buy more truck for the money today, but it also means future resale values may face some pressure if the market stays loose. If you plan to sell later, buying well matters more than usual because your eventual return will depend heavily on how much room you leave between purchase price and market average. 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:

• 34.6% of listings are priced as good or great deals.
• Price trend: Prices have softened 13.62% compared with last year.
• Owners rate it 4.28/5 — a solid satisfaction signal.

Consider the 2021 if:

• At $39,996 CAD, the 2021 costs more than the current year's $37,958 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 and a broader pool of discounted listings. If you are willing to spend more for a slightly newer truck with a more distinctive bed option, the 2021 is the better secondary path. For most price-sensitive buyers, though, the 2020 offers the stronger balance of market pricing and owner satisfaction.
