How much does the 2021 Mazda CX-30 cost?

Prices have softened 1.96% compared to this time last year, making it a favorable time to shop this model year.

There are 926 listings available, which gives you a useful amount of inventory to compare.

If you find a listing below $19,039.63, that's toward the low end of the year-round range and worth acting on quickly.

Is the 2021 Mazda CX-30 a good car?

Yes — the 4.77/5 user rating points to strong owner satisfaction, and the expert rating is 7.5/10. The standout strength is Safety at 9/10.

Owners consistently praise the CX-30’s sporty design, interior quality, and fun-to-drive nature. They also like the luxury feel at an affordable price, which fits the model’s upscale positioning. On the trade-off side, the expert review notes poor handling and fairly pedestrian performance, while owners mention limited back seat legroom and a desire for more USB ports.

That makes the CX-30 a strong fit if you want a small crossover that feels more premium than many mainstream rivals and still delivers everyday practicality. It also helps that 33.6% of listings are priced as good or great deals, so you have room to shop selectively.

Is the 2021 Mazda CX-30 reliable?

Owners rate it 4.77/5, a strong signal of long-term satisfaction.

The owner feedback points to a vehicle that feels fun to drive, well built, and satisfying over time, with the kind of sporty design and interior quality that tends to keep owners happy. The expert review also emphasizes confidence, capability, style, and satisfaction, which supports the impression of a well-rounded ownership experience. Mazda’s cost-effectiveness notes also frame the CX-30 Turbo as a thoughtful value play in its segment.

For used buyers, the main long-term risk is less about outright durability concerns and more about whether the specific vehicle has been maintained and used in a way that matches your expectations.

What should I look for when buying a used 2021 Mazda CX-30?

Accident-free inventory is solid at 79% — always verify the vehicle history report.

You should still check the history report carefully, because accident-free status is a starting point, not a guarantee. Prioritize a pre-purchase inspection that focuses on body condition, interior wear, and how the vehicle drives. Since owners mention limited back seat legroom and a desire for more USB ports, make sure the cabin layout and convenience features work for your needs.

Key things to evaluate:

• Trim level: The standard setup includes black or Griege leatherette upholstery, while Premium and Premium Plus add black or white leather, plus a frameless rearview mirror and a chrome accent around the engine start button.
• Powertrain: The turbocharged 2.5-liter four-cylinder pairs with a six-speed automatic and standard all-wheel drive. Output ranges from 227 to 250 horsepower depending on fuel octane, with 310 lb-ft at 2,000 rpm or 320 lb-ft at 2,500 rpm. Fuel economy is rated at 25 mpg combined.
• Safety package: Every CX-30 Turbo includes i-ActiveSense advanced driver assistance systems and a mobile 9-1-1 automatic emergency notification system. Premium trim adds adaptive front lighting, while Premium Plus adds front and rear parking sensors, rear automatic braking, a surround-view camera, and Traffic Jam Assist.
• Infotainment: The cabin uses an 8.8-inch display that is not a touchscreen. Standard Apple CarPlay and Android Auto are included, and Mazda Connected Services provides remote engine starting and vehicle finder functions. Premium and Premium Plus add SiriusXM, navigation, a 12-speaker Bose audio system, and an Active Driving Display.
• Fuel efficiency: The turbo model is rated at 25 mpg in combined driving, and the review notes an average of 24.1 mpg in testing.

Which 2021 Mazda CX-30 trim should I buy?

The 2021 Mazda CX-30 is offered in 3 trim levels: Premium, Premium Plus, and Turbo.

Here's the short version:

• Base trim: The standard setup gives you the core upscale cabin feel, but it skips the added convenience and visibility upgrades found higher up the range.
• Sweet-spot trim: Premium is the best value if you want a more polished experience, because it adds adaptive front lighting and keeps the CX-30’s upscale character intact.
• Premium/top trim: Premium Plus is the most fully equipped choice, adding front and rear parking sensors, rear automatic braking, a surround-view camera, Traffic Jam Assist, navigation, a Bose audio system, and an Active Driving Display.

Every CX-30 Turbo includes i-ActiveSense, and Premium Plus is the trim that layers on the most useful safety and convenience tech.

Is now a good time to buy a used 2021 Mazda CX-30?

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

• Deal availability: 33.6% of listings are priced as good or great deals.
• Inventory: There are 926 listings available.
• Price trend: Prices have softened 1.96% compared with last year.
• Clean inventory: 79.0% of listings are accident-free.

If you find a listing below $19,039.63, that's toward the low end of the year-round range and worth acting on quickly.

What is the 2021 Mazda CX-30's resale value?

The current average of $20,113 sits slightly below last year's $20,514.

That softer pricing suggests the market has eased a bit, which can help you buy more confidently now. For a future seller, it also means resale value may depend heavily on condition, mileage, and trim, since the model is already trading below its prior-year average. Strong presentation and a clean history should matter more when it comes time to list.

Vehicles with strong owner satisfaction ratings, like this model year's 4.77/5, tend to retain buyer demand, which supports resale value over time.

Is the 2021 Mazda CX-30 safe?

It earns a Top Safety Pick+ rating from the Insurance Institute for Highway Safety (IIHS), and it earns five-star ratings in every NHTSA assessment except rollover resistance, where it receives a four-star rating.

It earns a 9/10 safety score from our experts.

Every CX-30 Turbo comes with i-ActiveSense advanced driver assistance systems, and Mazda says they are effective without being overly irritating. Standard equipment also includes a mobile 9-1-1 automatic emergency notification system. Premium trim adds adaptive front lighting, while Premium Plus adds front and rear parking sensors, rear automatic braking, a surround-view camera, and Traffic Jam Assist.

One caveat is that there is no high-speed lane-centering assistance function, and Traffic Jam Assist can be intrusive if you try to let go of the wheel for too long.

Should I buy a 2021 Mazda CX-30 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:

• 33.6% of listings are priced as good or great deals.
• Accident-free inventory is solid at 79% — always verify the vehicle history report.
• Price trend: Prices have softened 1.96% compared with last year.
• Owners rate it 4.77/5 — a strong satisfaction signal.
• It blends premium design, strong safety, and upscale tech with a distinctive turbocharged character.

Consider the 2020 if:

• At $18,760, the 2020 costs less than the current year's $20,113 average.
• It offers extra ground clearance and easier entry and exit.

Consider the 2022 if:

• At $22,486, the 2022 costs more than the current year's $20,113 average.
• It adds a more spacious cabin and an even more upscale interior.

The bottom line: The 2021 is the best all-around pick if you want the CX-30’s upscale feel, strong safety, and turbocharged personality without paying newer-year pricing. If your budget is tighter, the 2020 is the value play; if you want a newer cabin and can spend more, the 2022 is worth a look.
