Should I buy a 2021 Ford Mustang or consider a different year?

If you're weighing the 2021 against nearby model years, here's how to think about it:

Choose the 2021 if:

• 28.9% of listings are priced as good or great deals.
• Price trend: Prices are up 1.21% year-over-year.
• Owners rate it 4.71/5 — a strong satisfaction signal.

Consider the 2020 if:

• At $35,073 CAD, the 2020 costs less than the current year's $41,935 CAD average.
• It offers strong value for performance-focused buyers.

The bottom line:
Choose the 2021 if you want the newer market position and are comfortable paying more for it. If your priority is value, the 2020 is the better secondary path because it delivers Mustang character at a lower entry price.
