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

The current average of $36,584 CAD sits slightly below last year's $42,807 CAD.

That price movement suggests the market has cooled, which can help you buy more affordably now but may also limit upside if you plan to resell soon.

Vehicles with solid owner satisfaction ratings, like this model year's 4.3/5, 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:

• 36.6% of listings are priced as good or great deals.
• Price trend: Prices have softened 14.54% compared with last year.
• Owners rate it 4.3/5 — a solid satisfaction signal.

Consider the 2021 if:

• At $38,293 CAD, the 2021 costs more than the current year's $36,584 CAD average.
• It adds a carbon-fibre composite cargo bed for extra utility.

The bottom line: Choose the 2020 if you want the better value and are comfortable shopping carefully within a broad used-truck market. Consider the 2021 if you want to spend more for a newer model year and a few extra features, but price-sensitive buyers will likely find the 2020 the smarter buy.
