Should I buy a 2021 Mazda CX-30 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:

• 26.5% of listings are priced as good or great deals.
• Price trend: Prices have softened 4.41% compared with last year.
• Owners rate it 4.8/5 — a strong satisfaction signal.
• It blends premium design, strong safety, and engaging driving dynamics.

Consider the 2022 if:

• At $24,974 CAD, the 2022 costs more than the current year's $24,576 CAD average.
• It adds a more spacious cabin and keeps the upscale feel.

The bottom line: If you want the better value today, the 2021 is the smarter buy because prices have eased and owner satisfaction is strong. If you are willing to spend a bit more for a newer model year with a roomier cabin, the 2022 is worth a look.
