Used 2021 Mazda CX-3 for SaleNationwide

How much does the 2021 Mazda CX-3 cost?

Prices have softened 14.05% compared to this time last year, making it a favourable time to shop this model year.

There are 94 listings available, which suggests a modest amount of inventory for shoppers comparing options.

Is the 2021 Mazda CX-3 a good car?

Yes — the 5/5 user rating points to strong owner satisfaction, and the 2021 Mazda CX-3’s overview backs that up with a stylish design, a fun driving character, and a premium-feeling cabin for the class. It also suits you if you want a used subcompact SUV that feels more polished than basic, especially if you value efficiency, safety equipment, and engaging road manners over maximum room. The market also shows 35.1% of listings as good or great deals, which gives you some room to shop selectively.

Is the 2021 Mazda CX-3 reliable?

Owners rate it 5/5, a strong signal of long-term satisfaction.

The 2021 Mazda CX-3’s overview also points to a solid list of driver-assist safety features and top safety ratings from the U.S. National Highway Traffic Safety Administration and the Insurance Institute for Highway Safety. For used buyers, the main long-term ownership risk is less about outright dependability and more about whether the cramped back seat and limited cargo space will still fit your needs over time.

Is now a good time to buy a used 2021 Mazda CX-3?

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

• Deal availability: 35.1% of listings are priced as good or great deals.
• Inventory: There are 94 listings available.
• Price trend: Prices have softened 14.05% compared with last year.

If you find a listing below $20,119 CAD, that's toward the low end of the year-round range and worth acting on quickly.

What is the 2021 Mazda CX-3's resale value?

The current average of $20,382 CAD sits slightly below last year's $23,714 CAD.

That price movement suggests the CX-3 has become more accessible for buyers, which can make it easier to sell into a value-conscious market later. For you as a future seller, the softer pricing trend means resale expectations should stay realistic rather than aggressive. Even so, the model’s strong owner satisfaction can help support demand when you decide to list it.

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 2021 Mazda CX-3 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:

• 35.1% of listings are priced as good or great deals.
• Price trend: Prices have softened 14.05% compared with last year.
• Owners rate it 5/5 — a strong satisfaction signal.

The bottom line: If you want the strongest mix of value, owner satisfaction, and a polished driving feel, the 2021 is the one to target first. If you’re especially price-sensitive, you can also compare nearby years and focus on whichever listing gives you the best condition and equipment for the money.
