What is the 2023 GMC Sierra 2500HD's resale value?

The current average of $65,423 CAD sits slightly below last year's $72,655 CAD.

That softer pricing can help you buy in at a more favourable point, but it also means future resale gains may be more limited if the market stays soft. For a seller, the current trend suggests you may need to price competitively to move the truck. Strong equipment and premium trims can still help attract buyers, especially in a segment where capability and comfort both matter.

Vehicles with solid owner satisfaction ratings, like this model year's 4/5, tend to retain buyer demand, which supports resale value over time.

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

If you're weighing the 2023 against nearby model years, here's how to think about it:

Choose the 2023 if:

• 29.1% of listings are priced as good or great deals.
• Price trend: Prices have softened 9.95% compared with last year.
• Owners rate it 4/5 — a solid satisfaction signal.

Consider the 2022 if:

• At $59,546 CAD, the 2022 costs less than the current year's $65,423 CAD average.
• It balances serious capability with everyday usability.

Consider the 2024 if:

• At $77,658 CAD, the 2024 costs more than the current year's $65,423 CAD average.
• It adds the Denali Ultimate and a more luxurious, capability-focused setup.

The bottom line: The 2023 is the best all-around choice if you want the newer truck’s upscale feel and broader trim spread without stepping up to the 2024’s higher price. If your priority is saving money first, the 2022 is the better value path, while the 2024 makes sense if you want the most premium and capability-rich version.
