Is the 2018 Mazda CX-3 a good car?

Yes — the 2018 Mazda CX-3 earns a 5/5 user rating and an 8.00/10 expert rating. The model scores 9/10 across Performance and Safety.

The standard maintenance and ownership experience should be manageable for a used buyer, but you should still verify service history and overall condition before committing.

What should I look for when buying a used 2018 Mazda CX-3?

At 65% 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 pre-purchase inspection, especially if the listing price looks unusually attractive. Focus on body condition, signs of prior repair, and whether the cabin and cargo area show wear that matches the mileage.

Key things to evaluate:

• Trim level: The base Sport trim includes a 7-inch touchscreen, reversing camera, app integration through Mazda Connect, cruise control, Bluetooth, air conditioning, and a 6-speaker stereo, while the Touring adds larger 18-inch alloys, auto headlights and wipers, heated seats, a leather-wrapped steering wheel, auto climate controls, heated mirrors, proximity entry, and blind-spot monitoring with rear cross-traffic alerts. The Grand Touring adds full exterior LEDs, leather-trimmed seats with Alcantara inserts, a head-up display, paddle shifters, and navigation.
• Powertrain: Every CX-3 uses a 2.0-liter, 4-cylinder engine with a 6-speed automatic transmission. It makes 146 hp and 146 lb-ft of torque, and the review notes that it delivers strong enough response for the class while returning about 31 mpg combined.
• Safety package: The CX-3 includes low-speed emergency braking as standard, and the Touring trim adds blind-spot monitoring with rear cross-traffic alerts. The Premium Package adds upgraded forward-collision warning and auto-braking, adaptive cruise, lane-departure warning, auto high beams, and traffic-sign recognition.
• Infotainment: The standard setup uses a 7-inch touchscreen with Mazda Connect, but the rotary-controlled interface can take time to learn. Android Auto and Apple CarPlay are not included.
• Fuel efficiency: The CX-3 is rated at 31 mpg combined, 29 mpg city, and 34 mpg highway.

Which 2018 Mazda CX-3 trim should I buy?

The 2018 Mazda CX-3 is offered in 3 trim levels: Sport, Touring, Grand Touring.

Here's the short version:

• Sport: This is the value play if you want the CX-3’s core strengths at the lowest entry point. You still get the redesigned suspension, standard low-speed emergency braking, a 7-inch touchscreen, reversing camera, app integration, and the same 2.0-liter engine as the pricier trims.
• Touring: This is the best-value trim for most shoppers because it adds the most useful everyday upgrades, including heated seats, auto climate controls, proximity entry, and blind-spot monitoring with rear cross-traffic alerts. The available Preferred Equipment Package also makes it easier to add desirable comfort and audio upgrades.
• Grand Touring: Choose this if you want the most upscale CX-3 experience, with leather-trimmed seats with Alcantara inserts, navigation, a head-up display, paddle shifters, and full exterior LEDs. If you want the most advanced safety tech, this is also the trim that pairs best with the Premium Package.

Mazda notes that the Touring trim gets some advanced safety systems, while the Premium Package is the route to the most complete safety setup.

Is now a good time to buy a used 2018 Mazda CX-3?

The market looks moderate and selective, so you can shop with some leverage if you compare listings carefully.

• Deal availability: 30.5% of listings are priced as good or great deals.
• Inventory: There are 266 listings available.
• Price trend: Prices have held steady compared with last year.
• Clean inventory: 65.0% of listings are accident-free.

If you find a listing below $14,317, that's toward the low end of the year-round range and worth acting on quickly.

What is the 2018 Mazda CX-3's resale value?

The current average of $15,270 sits slightly below last year's $15,311.

That small decline suggests the CX-3 has been holding value fairly steadily rather than swinging sharply up or down. For a future seller, that kind of pricing pattern usually points to a market that is predictable, which can make it easier to estimate your trade-in or private-party outcome.

Because the current average is close to last year’s level, you should expect resale performance to depend more on condition, mileage, and history than on broad market movement. Well-kept examples should remain easier to move than neglected ones.

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 2018 Mazda CX-3 safe?

The 2018 Mazda CX-3 is a Top Safety Pick+ from IIHS and earns a five-star rating from NHTSA.

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

The standard safety story is a strong one for this model year, with low-speed emergency braking added across the lineup. Mazda also makes more advanced safety systems available on higher trims, and the Touring trim gets blind-spot monitoring with rear cross-traffic alerts.

One caveat is that the most advanced safety content is not spread evenly across the lineup, so you should check trim and package details carefully if safety tech matters most to you.

Should I buy a 2018 Mazda CX-3 or consider a different year?

If you're weighing the 2018 against nearby model years, here's how to think about it:

Choose the 2018 if:

• 30.5% of listings are priced as good or great deals.
• At 65% 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 2018 adds standard low-speed emergency braking and a more comfortable cabin.

Consider the 2019 if:

• At $15,914, the 2019 costs more than the current year's $15,270 average.
• It adds a more polished, upscale feel with a stronger emphasis on style and sophistication.

The bottom line: If you want the better value and a more stable price point, the 2018 is the smarter starting point. If you’re willing to pay more for a fresher-feeling, more premium presentation, the 2019 is the better alternative.
