Used 2020 Mazda MAZDA3 for Sale nearLos Angeles, CA

How much does the 2020 Mazda MAZDA3 cost?

Prices have softened 4.84% compared to this time last year, making it a favorable time to shop this model year.

There are 500 listings available, which suggests you have a workable amount of inventory to compare.

If you find a listing below $17,073.93, that's toward the low end of the year-round range and worth acting on quickly.

Is the 2020 Mazda MAZDA3 a good car?

Yes — the 2020 Mazda MAZDA3 earns a 5/5 user rating, and our experts rate it 7.83/10. The standout strength is Safety at 10/10.

You also get recurring praise for its stunning design, amazing interior, and enjoyable driving experience. The model’s upscale feel and advanced safety features are a big part of why it appeals to you if you want a compact car that feels more premium than basic.

The trade-offs are clear: it can feel underpowered in everyday acceleration, and it has limited cargo space. It fits you best if you value style, refinement, and safety more than maximum practicality.

With 29.8% of listings marked as good or great deals, there’s still room to shop selectively.

Is the 2020 Mazda MAZDA3 reliable?

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

The owner feedback points to a car that many drivers feel good about living with over time, with language centered on a dependable and trouble-free ownership experience. That kind of feedback matters when you’re shopping used, because it suggests the car has earned trust beyond its styling and driving feel.

The expert notes also support that impression by describing the engine as good and predictable, which reinforces the sense that the car is easy to count on in daily use. Mazda’s maintenance messaging also helps ownership feel less burdensome.

For you as a used buyer, the main long-term risk is less about headline reliability and more about finding a well-kept example that hasn’t been worn down by age, mileage, or neglect.

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

At 70.8% 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 careful inspection of bodywork, panel alignment, and signs of prior repair. Because this model emphasizes style and refinement, condition matters a lot: you’ll want to focus on how the cabin, exterior finish, and mechanical feel have held up.

Key things to evaluate:

• Trim level: The base trim is missing the 18-inch alloy wheels that come standard on all but the base-trim-level vehicle, so you should check whether the features you want are included before you pay more for a higher trim.
• 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 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 Acceptable headlights, while the Premium Package’s LED headlights are rated Good.
• Infotainment: You get an 8.8-inch display, Apple CarPlay, Android Auto, Bluetooth, and a rotary controller instead of touchscreen operation. The system is quick and sharp-looking, but it takes some adjustment.
• Fuel efficiency: The EPA says it returns 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 better-value choice if you want the Mazda3’s upscale design, standard safety equipment, and easy-to-use tech without stretching to the top of the range. It gives you the core appeal of the car while keeping the price more manageable.
• Premium: Choose this if you want the most polished version of the Mazda3, especially if you care about the richer cabin feel and the stronger feature set that comes with the higher package. It makes the most sense if you’re prioritizing comfort and presentation over budget.

The safety-package note to keep in mind is that the Premium Package’s LED headlights earn a Good rating, while lower trims receive Acceptable headlights.

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

This looks like a moderate, selective buyer’s market, so you can shop carefully without feeling rushed.

• Deal availability: 29.8% of listings are priced as good or great deals.
• Inventory: There are 500 listings available.
• Price trend: Prices have softened 4.84% compared with last year.
• Clean inventory: 70.8% of listings are accident-free.

If you find a listing below $17,073.93, 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 $17,997 sits slightly below last year's $18,913.

That softer pricing can help you buy in at a more favorable point, but it also means future resale gains may be more limited if the market stays soft. If you plan to sell later, condition and mileage will matter even more because buyers will have plenty of comparable listings to choose from.

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?

Labeled a Top Safety Pick+ by the Insurance Institute for Highway Safety (IIHS), the Mazda3 received a five-star overall safety rating from the National Highway Traffic Safety Administration (NHTSA), scoring top marks 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. That gives you a strong standard safety foundation for a compact car.

One caveat is that lower trim levels get Acceptable headlights, while the Premium Package’s LED headlights are rated Good. If safety is a top priority, that trim-level difference is worth paying attention to.

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:

• 29.8% of listings are priced as good or great deals.
• At 70.8% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.
• Price trend: Prices have softened 4.84% 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 $16,850, the 2019 costs less than the current year's $17,997 average.
• It makes a compact car feel upscale, refined, and genuinely athletic.

Consider the 2021 if:

• At $19,499, the 2021 costs more than the current year's $17,997 average.
• It adds turbocharged power with a more refined, upscale character.

The bottom line: If you want the best balance of style, safety, and current-market pricing, the 2020 is the primary path to consider. If you’re more price-sensitive, the 2019 is the cheaper alternative; if you want a newer and more powerful direction, the 2021 is the upgrade path.
