Used 2021 Mazda MAZDA3 for Sale nearKenosha, WI

How much does the 2021 Mazda MAZDA3 cost?

Prices have held steady compared to this time last year, signaling a stable and predictable market for this model year.

There are 601 listings available, which gives you a solid amount of inventory to compare.

Is the 2021 Mazda MAZDA3 a good car?

Yes — the 2021 Mazda MAZDA3 earns a 5/5 user rating and an 8.3/10 expert rating. The model scores 10/10 across Look and feel, Cost effectiveness, and Safety.

Owners consistently praise its sporty design, high-quality interior, and fun driving experience, and they also call out its fuel efficiency. In use, that lines up well with the car’s appeal as a compact model that feels more refined and engaging than many mainstream rivals.

The main trade-offs are that the manual transmission is not available, visibility is poor, and the technology feels outdated. That makes it a stronger fit if you want style, cabin quality, and driving enjoyment more than maximum practicality or the latest interface tech.

The market also looks reasonably healthy, with 36.3% of listings marked as good or great deals.

Is the 2021 Mazda MAZDA3 reliable?

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

The owner feedback also points to a car that feels dependable and trouble-free in everyday use, with praise centered on its quality, driving enjoyment, and fuel efficiency. The expert review reinforces that impression by describing the powertrain and dynamic tuning as smooth, consistent, and predictable, and by noting that the car is one you can come to know and trust.

The cost-effectiveness discussion also suggests strong value for the money, which can help reduce ownership regret over time. For used buyers, the main long-term risk is less about outright durability and more about whether the car’s premium feel and technology age in a way you can live with.

What should I look for when buying a used 2021 Mazda MAZDA3?

At 70% 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 bodywork, panel alignment, and signs of prior repair. It’s also smart to focus on cabin condition and technology operation, since the car’s appeal depends heavily on its premium feel and equipment working properly.

Key things to evaluate:

• Trim level: The Premium Plus trim adds a more upscale cabin with Nappa leather, a high-definition surround-view camera, front and rear parking sensors, low-speed reverse automatic braking, and Traffic Jam Assist, while the standard setup uses leatherette and fewer premium touches.
• Powertrain: The turbocharged 2.5-liter four-cylinder pairs with a six-speed automatic and all-wheel drive, and it delivers strong performance with smooth, predictable response.
• Safety package: The i-ActiveSense suite includes adaptive cruise control with stop-and-go capability and automatic high-beam LED headlights with Adaptive Front Lighting System; Premium Plus adds exclusive features like the surround-view camera, parking sensors, reverse automatic braking, and Traffic Jam Assist.
• Infotainment: Mazda Connect uses an 8.8-inch display with Apple CarPlay, Android Auto, and a three-year trial of Mazda Connected Services, but the screen is not touch-sensitive.
• Fuel efficiency: The turbo model averaged 20.4 mpg in testing, with an EPA estimate of 27 mpg combined and an expected real-world figure of about 24 mpg.

Which 2021 Mazda MAZDA3 trim should I buy?

The 2021 Mazda MAZDA3 is offered in 2 trim levels: standard and Premium Plus.

Here's the short version:

• standard: This is the better value if you want the Mazda3’s core strengths — stylish design, premium materials, strong safety tech, and the engaging driving character — without paying for the extra luxury and parking aids.
• Premium Plus: Choose this if you want the most upscale version, with Nappa leather, the surround-view camera, front and rear parking sensors, reverse automatic braking, and Traffic Jam Assist.

The safety package is a strong part of the lineup, and the available driver-assistance tech is one of the Mazda3’s biggest strengths.

Is now a good time to buy a used 2021 Mazda MAZDA3?

This is a moderate market, so you can be selective without expecting a deep buyer’s market.

• Deal availability: 36.3% of listings are priced as good or great deals.
• Inventory: There are 601 listings available.
• Price trend: Prices have held steady compared with last year.
• Clean inventory: 70.0% of listings are accident-free.

If you find a listing below $18,449, that's toward the low end of the year-round range and worth acting on quickly.

What is the 2021 Mazda MAZDA3's resale value?

The current average of $19,118 sits slightly above last year's $19,073.

That small increase suggests the market has stayed stable rather than swinging sharply in either direction. For a future seller, that kind of pricing pattern is helpful because it points to steady demand and fewer signs of rapid depreciation pressure.

The model’s strong owner satisfaction also supports long-term appeal in the used market. If you keep the car in good condition and maintain its premium presentation, it should remain attractive to shoppers looking for a stylish compact car.

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 2021 Mazda MAZDA3 safe?

The 2021 Mazda MAZDA3 earns five-star ratings in every NHTSA assessment, including rollover resistance, and it had previously carried an IIHS Top Safety Pick+ rating.

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

Mazda’s i-ActiveSense suite is the core driver-assistance package, and it’s designed to support the driver rather than replace them. Standard features include adaptive cruise control with stop-and-go capability and automatic high-beam LED headlights with Adaptive Front Lighting System, while Premium Plus adds a high-definition surround-view camera, front and rear parking sensors, low-speed reverse automatic braking, and Traffic Jam Assist.

The main caveat is that the IIHS note references the earlier Top Safety Pick+ recognition rather than confirming it for this review period.

Should I buy a 2021 Mazda MAZDA3 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:

• 36.3% of listings are priced as good or great deals.
• At 70% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.
• Price trend: Prices have held steady compared with last year.
• Owners rate it 5/5 — a strong satisfaction signal.
• The turbocharged version delivers smooth, predictable performance with a more premium feel.

Consider the 2020 if:

• At $17,619, the 2020 costs less than the current year's $19,118 average.
• It emphasizes premium styling, easy-to-use tech, and standard advanced safety features.

Consider the 2022 if:

• At $20,302, the 2022 costs more than the current year's $19,118 average.
• It adds fresh appearance and equipment updates, including Carbon Edition and Turbo enhancements.

The bottom line: If you want the best balance of price stability, strong owner satisfaction, and premium character, the 2021 is the smart default. If you’re more price-sensitive, the 2020 is the value play; if you want the newest updates, look to the 2022.
