That price movement suggests the CX-9 has become more affordable in the used market, which can help you buy at a better entry point today.

Should I buy a 2020 Mazda CX-9 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:

• 39.7% of listings are priced as good or great deals.
• At 63.3% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.
• Price trend: Prices have softened 10.18% compared with last year.
• Owners rate it 4.9/5 — a strong satisfaction signal.

Consider the 2019 if:

• At $17,511, the 2019 costs less than the current year's $18,925 average.
• It offers roomy, safe family-hauling with stylish handling.

Consider the 2021 if:

• At $21,586, the 2021 costs more than the current year's $18,925 average.
