Is now a good time to buy a used 2020 Mazda MAZDA6?

This looks like a moderate, selective buyer's market, so you can shop carefully and still find value.

What is the 2020 Mazda MAZDA6's resale value?

The current average of $17,994 sits slightly below last year's $18,860.

That softer pricing can help you buy at a more favorable entry point, but it also means future resale gains may be more limited if the market stays steady. If you plan to sell later, condition and mileage will matter even more because buyers tend to respond strongly to well-kept examples in a market with moderate price pressure.

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:

• 29.3% of listings are priced as good or great deals.
• At 62.2% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.
• Price trend: Prices have softened 4.59% compared with last year.
• Owners rate it 4.86/5 — a strong satisfaction signal.

Consider the 2021 if:

• At $20,368, the 2021 costs more than the current year's $17,994 average.
• It adds a more refined feel with premium materials and a more enjoyable driving experience.

The bottom line:
You should start with the 2020 if you want the better value and a strong owner-satisfaction profile. If you can stretch your budget and want a more polished-feeling alternative, the 2021 is the better secondary path.
