Is now a good time to buy a used 2020 Mazda MAZDA3?

This looks like a moderate, selective buyer’s market, so you can shop carefully and still find worthwhile listings.

• Deal availability: 34.7% of listings are priced as good or great deals.
• Inventory: There are 167 listings available.
• Price trend: Prices have softened 6.95% compared with last year.

If you find a listing below $19,201 CAD, that's toward the low end of the year-round range and worth acting on quickly.

What is the 2020 Mazda MAZDA3's resale value?

The current average of $19,614 CAD sits slightly below last year's $21,078 CAD.

That softer pricing can help you buy in at a more favourable point, but it also means future resale gains may be more limited if the market stays soft. If you plan to sell later, the current trend suggests you should focus on condition, mileage, and service records to protect value. Strong presentation and a clean history will matter more when the market is already pricing this model more competitively.

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

Should I buy a 2020 Mazda MAZDA3 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:

• 34.7% of listings are priced as good or great deals.
• Price trend: Prices have softened 6.95% compared with last year.
• Owners rate it 5/5 — a strong satisfaction signal.

Consider the 2021 if:

• At $20,980 CAD, the 2021 costs more than the current year's $19,614 CAD average.
• It adds a turbocharged engine for stronger performance.

The bottom line: The 2020 is the better starting point if you want the stronger value proposition and a wider pool of lower-priced listings. If you’re willing to pay more for extra performance, the 2021 is the better upgrade path; if you’re price-sensitive, the 2020 gives you the smarter buy.
