The current average of $18,085 sits slightly below last year's $18,868.

That softer pricing can work in your favor if you're buying now, but it also means future resale may depend heavily on how well you preserve the car's condition and documentation.

Vehicles with strong owner satisfaction ratings, like this model year's 4.86/5, tend to retain buyer demand, which supports resale value over time.

Should I buy a 2020 Mazda MAZDA6 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:

• 31.9% of listings are priced as good or great deals.
• At 62% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.
• Price trend: Prices have softened 4.15% compared with last year.
• Owners rate it 4.86/5 — a strong satisfaction signal.

Consider the 2021 if:

• At $20,328, the 2021 costs more than the current year's $18,085 average.
• It adds a more refined style-and-quality focus with a more enjoyable steering feel.

The bottom line: If you want the better value play, the 2020 is the smarter starting point because pricing has eased and shopper satisfaction is strong. If you're willing to spend more for a newer model year and a slightly more polished feel, the 2021 is the better secondary path for buyers who prioritize refinement over savings.
