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:

• 31.8% of listings are priced as good or great deals.
• Price trend: Prices have softened 11.25% compared with last year.
• Owners rate it 4.28/5 — a solid satisfaction signal.

Consider the 2021 if:

• At $39,770 CAD, the 2021 costs more than the current year's $38,388 CAD average.
• It adds an optional carbon-fibre composite cargo bed.

The bottom line: The 2020 is the better starting point if you want stronger value and a wider pool of listings to compare. If you are price-sensitive, the 2020 makes more sense; if you want the newer-year feature set and do not mind paying more, the 2021 is worth a look.
