How much does the 2020 Mazda MAZDA3 cost?

Prices have softened 3.48% compared to this time last year, making it a favorable time to shop this model year.

There are 528 listings available, which suggests you have a workable amount of inventory to compare.

Is the 2020 Mazda MAZDA3 a good car?

Yes — the 2020 Mazda MAZDA3 earns a 5/5 user rating and a 7.83/10 expert rating. The standout strength is Safety at 10/10.

Drivers consistently praise the car’s stunning design, amazing interior, and enjoyable driving experience. The feedback also points to a luxurious feel and advanced safety features, which fits a car that aims to feel more premium than a typical compact.

The main trade-offs are a lack of power and limited cargo space. That means you should view it as a style-and-features pick first, especially if you want a compact car that feels upscale and easy to live with rather than maximally practical.

The model’s appeal is strongest if you want a well-equipped small car with a premium atmosphere, stylish design, and everyday usability. With 30.7% of listings marked as good or great deals, there is still room to shop selectively.

Is the 2020 Mazda MAZDA3 reliable?

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

User feedback points to a car that feels dependable and trouble-free enough to inspire confidence over time, with owners especially appreciating the way it delivers a refined ownership experience. The expert evaluation also describes the engine as good and predictable, which supports the sense that the car is easy to count on in daily use.

Mazda also includes a first scheduled maintenance visit at no charge, which helps soften early ownership costs. For used buyers, the bigger long-term risk is less about outright durability and more about choosing a well-kept example that has been maintained properly.

What should I look for when buying a used 2020 Mazda MAZDA3?

At 71% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.

You should start with a vehicle history report and then prioritize a close inspection of body panels, paint consistency, and signs of prior repair. Because this model emphasizes style and premium feel, condition matters a lot: worn interior materials, rough exterior finish, or evidence of poor repairs can undermine the car’s appeal quickly.

Key things to evaluate:

• Trim level: The Premium Package adds 18-inch alloy wheels, a blacked-out mesh front grille, round running lamps, creamy white leather, and a more upscale cabin feel. The base-trim-level vehicle misses the 18-inch alloy wheels, and lower trim levels also receive less capable headlights than the Premium Package.
• Powertrain: All 2020 Mazda3s use a 2.5-liter SkyActiv four-cylinder engine with 186 horsepower and 186 pound-feet of torque. The engine is good and predictable, but it lacks the immediate punch of turbocharged rivals.
• Safety package: Mazda offers forward-collision warning, lane-departure warning, adaptive cruise control, automatic emergency braking, blind-spot monitoring, rear cross-traffic alert, and dynamic brake support. Lower trim levels receive an Acceptable score for their headlights.
• Infotainment: The cabin centers on an 8.8-inch display, and Mazda does not include touchscreen functionality. Apple CarPlay and Android Auto are included, along with Bluetooth connectivity, and the system is controlled by a rotary dial.
• Fuel efficiency: The EPA says it will return 25 mpg in the city and 33 mpg on the highway.

Which 2020 Mazda MAZDA3 trim should I buy?

The 2020 Mazda MAZDA3 is offered in 2 trim levels: Preferred and Premium.

Here's the short version:

• Preferred: This is the trim to target if you want the Mazda3’s core strengths without stretching too far. You still get the car’s stylish design, easy-to-use technology, and standard advanced safety features, while avoiding the highest pricing tier.
• Premium: Choose this if you want the more upscale presentation and the strongest feature set. The Premium Package brings 18-inch alloy wheels, a blacked-out mesh grille, round running lamps, creamy white leather, and the better headlight rating mentioned in the safety content.

The safety package is a major part of the Mazda3’s appeal, and the Premium Package stands out for its stronger headlight performance.

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

This is a moderate market for selective buyers, so you can shop with some leverage if you stay patient.

• Deal availability: 30.7% of listings are priced as good or great deals.
• Inventory: There are 528 listings available.
• Price trend: Prices have softened 3.48% compared with last year.
• Clean inventory: 71.0% of listings are accident-free.

If you find a listing below $17,071, 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 $18,228 sits slightly below last year's $18,884.

That softer pricing suggests the market has become a bit more buyer-friendly, which can work against short-term resale gains if you buy at the wrong point. If you plan to sell later, your best protection is to buy well, keep mileage reasonable, and maintain the car carefully so it stands out in a value-conscious segment.

Because the model still attracts shoppers looking for style, safety, and a premium feel, well-kept examples should continue to draw interest. Vehicles with strong owner satisfaction ratings, like this model year's 5/5, tend to retain buyer demand, which supports resale value over time.

Is the 2020 Mazda MAZDA3 safe?

The 2020 Mazda MAZDA3 earns a Top Safety Pick+ rating from IIHS and five-star ratings from NHTSA in all crash tests.

It earns a 10/10 safety score from our experts.

Mazda includes a broad suite of driver-assistance features: forward-collision warning, lane-departure warning, adaptive cruise control, automatic emergency braking, blind-spot monitoring, rear cross-traffic alert, and dynamic brake support. Lower trim levels do have a headlight gap versus the Premium Package, which is worth noting if safety equipment is a priority.

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:

• 30.7% of listings are priced as good or great deals.
• At 71% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.
• Price trend: Prices have softened 3.48% compared with last year.
• Owners rate it 5/5 — a strong satisfaction signal.
• It combines upscale styling, standard advanced safety features, and a premium-feeling cabin.

Consider the 2019 if:

• At $16,801, the 2019 costs less than the current year's $18,228 average.
• It makes a small car feel upscale, refined, and genuinely athletic.

Consider the 2021 if:

• At $19,625, the 2021 costs more than the current year's $18,228 average.
• Turbo power adds boosted performance with a more refined, upscale character.

The bottom line: The 2020 is the right pick if you want the Mazda3’s style, safety, and premium atmosphere at a more favorable price than the 2021. If you’re more price-sensitive, the 2019 is the value play, while the 2021 makes sense if you want the extra performance and are willing to pay more for it.
