The current average of $65,832 CAD sits slightly below last year's $71,379 CAD.

That softer pricing can help you buy more truck for the money today, but it also means future sellers may need to price competitively if the market stays loose.

Should I buy a 2023 GMC Sierra 2500HD or consider a different year?

Choose the 2023 if:

• 29.6% of listings are priced as good or great deals.
• Price trend: Prices have softened 7.77% compared with last year.
• Owners rate it 4/5 — a solid satisfaction signal.

Consider the 2022 if:

• At $60,560 CAD, the 2022 costs less than the current year's $65,832 CAD average.
• It balances serious capability with everyday usability.

Consider the 2024 if:

• At $77,722 CAD, the 2024 costs more than the current year's $65,832 CAD average.
• It adds the newly available Denali Ultimate trim with nearly every option.

The bottom line: The 2023 is the best all-around choice if you want a premium-feeling heavy-duty truck at a more approachable price than the 2024. If your priority is saving money, the 2022 is the better value play, while the 2024 makes sense if you want the newest upscale features and are willing to pay more.
