Used 2021 Mazda MAZDA6 for Sale nearPittsburgh, PA

How much does the 2021 Mazda MAZDA6 cost?

Prices are up 1.38% year-over-year — a sign of continued demand for this model year.

There are 178 listings available, which suggests a fairly limited pool of used Mazda6s to shop from.

Is the 2021 Mazda MAZDA6 a good car?

Yes — the 2021 Mazda MAZDA6 earns a 5/5 user rating and an 8/10 expert rating. The model scores 9/10 across Look and feel, Performance, and Safety.

It stands out as a stylish, high-quality family-sized four-door that is aimed squarely at drivers who care about the experience behind the wheel. The trade-off is that all-wheel drive is not available and the technology is outdated, so you are buying more for driving enjoyment and refinement than for the latest features.

The expert review also points to a car that is especially rewarding on the road, with a steering feel and overall driving character that make it a strong fit if you want a midsize sedan that feels more engaging than average. The 27.0% share of good or great deals suggests there are still some attractive listings if you shop carefully.

Is the 2021 Mazda MAZDA6 reliable?

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

The Mazda6 is described as a well-equipped, safe, and enjoyable sedan rather than a bargain-basement model, which can help support confidence in ownership. Its active safety systems are standard across the lineup, and the car’s overall design is presented as mature and proven rather than experimental.

The performance notes also emphasize smooth, predictable behavior from the drivetrain and chassis, which is a good sign for day-to-day dependability. For used buyers, the main long-term ownership risk is less about outright mechanical drama and more about accepting an older platform with dated technology and no available all-wheel drive.

What should I look for when buying a used 2021 Mazda MAZDA6?

At 63.5% 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 you are considering a higher-mileage example or one with a lower asking price. Focus on body condition, signs of prior repair, and whether the car’s equipment matches the trim level you expect.

Key things to evaluate:

• Trim level: The Sport and Touring use a 186-horsepower Skyactiv 2.5-liter four-cylinder engine, while the rest get a turbocharged 250-hp version of that powerplant. The Carbon Edition is based on the Grand Touring Reserve trim level and adds exclusive Polymetal Gray paint, red leather and contrast stitching, and black metallic wheels, while the Signature brings premium Nappa leather, Sen wood trim, LED interior lighting, and other luxury touches.
• Powertrain: Most versions use a turbocharged 2.5-liter four-cylinder engine with 250 hp and 320 pound-feet of torque on 93-octane fuel, or 227 hp and 310 lb-ft on regular gas. A six-speed automatic transmission with Sport mode sends power to the front wheels, and all-wheel drive is not available.
• Safety package: Every 2021 Mazda6 includes adaptive cruise control with stop-and-go capability, forward-collision warning with pedestrian detection, automatic emergency braking, blind-spot monitoring, rear cross-traffic alert, lane-departure warning, lane-keep assist, automatic high-beam headlights, and rain-sensing windshield wipers. Grand Touring Reserve adds adaptive headlights, a wiper de-icer system, and an Active Driving Display, while Signature adds driver-attention alert, traffic-sign recognition, rear automatic braking, a surround-view camera system, and front and rear parking sensors.
• Infotainment: The Mazda6 uses an 8-inch screen and the first-generation Mazda Connect system. It includes Bluetooth, Apple CarPlay, Android Auto, HD Radio, internet radio, text-messaging support, and E911 automatic emergency notification. Grand Touring trim or higher adds wireless Apple CarPlay, while Android Auto remains wired.
• Fuel efficiency: The turbocharged Mazda6 gets 26 mpg in combined driving, and testing returned 26.1 mpg.

Which 2021 Mazda MAZDA6 trim should I buy?

The 2021 Mazda MAZDA6 is offered in 6 trim levels: Sport, Touring, Grand Touring, Grand Touring Reserve, Carbon Edition, and Signature.

Here's the short version:

• Sport: This is the entry point, and it gives you the Mazda6’s core appeal: stylish design, a premium-feeling cabin, and the standard safety suite. It is the trim to consider if you want the lowest-cost way into the model and care more about the driving experience than extra luxury features.
• Touring: This trim keeps the same 186-horsepower engine as Sport but adds more equipment while staying on the value side of the lineup. It makes sense if you want a better-equipped Mazda6 without jumping to the turbocharged versions.
• Grand Touring: This is the best-value trim for many shoppers because it unlocks the turbocharged engine and adds wireless Apple CarPlay, an 11-speaker Bose premium audio system, and three free months of SiriusXM satellite radio. If you want the strongest mix of features and performance, this is the one to target.
• Grand Touring Reserve: This trim builds on Grand Touring with more upscale safety and convenience gear, including adaptive headlights, a wiper de-icer system, and an Active Driving Display. It suits you if you want a more premium daily driver and value added visibility and convenience features.
• Carbon Edition: Based on Grand Touring Reserve, this trim adds distinctive styling touches like Polymetal Gray paint, red leather, contrast stitching, and black metallic wheels. It is the pick if you want the Mazda6 to stand out visually without moving all the way to Signature.
• Signature: This is the luxury-leaning choice, with premium Nappa leather, Sen wood trim, LED interior lighting, an embedded navigation system, driver-attention alert, traffic-sign recognition, rear automatic braking, a surround-view camera system, and front and rear parking sensors. Choose it if you want the most upscale Mazda6 experience.

The safety package is standard across the lineup, but the higher trims add meaningful convenience and driver-assistance upgrades that make them easier to live with.

Is now a good time to buy a used 2021 Mazda MAZDA6?

The market looks moderate and selective, so you can shop with some leverage if you are patient and focused.

• Deal availability: 27.0% of listings are priced as good or great deals.
• Inventory: There are 178 listings available.
• Price trend: Prices are up 1.38% year-over-year.
• Clean inventory: 63.5% of listings are accident-free.

If you find a listing below $18,727, that's toward the low end of the year-round range and worth acting on quickly.

What is the 2021 Mazda MAZDA6's resale value?

The current average of $20,368 sits slightly above last year's $20,091.

That modest increase suggests the Mazda6 has held value reasonably well for a midsize sedan, especially given its older platform and niche appeal. If you buy one in good condition, you are starting from a price point that has already shown some resilience rather than a steep decline.

For a future seller, that can be encouraging because a car with a stable price trend is often easier to move when it is time to trade or sell privately. The limited inventory also helps support demand, especially for well-kept examples with desirable trims and clean history.

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 MAZDA6 safe?

The Mazda6 earns Top Safety Pick+ recognition from IIHS and five-star ratings in nearly every assessment from NHTSA.

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

Mazda bundles its active safety features under the i-Activesense banner, and every 2021 Mazda6 includes adaptive cruise control with stop-and-go capability, forward-collision warning with pedestrian detection, automatic emergency braking, blind-spot monitoring, rear cross-traffic alert, lane-departure warning, lane-keep assist, automatic high-beam headlights, and rain-sensing windshield wipers.

Starting with Grand Touring Reserve, you also get adaptive headlights, a wiper de-icer system, and an Active Driving Display. Signature adds driver-attention alert, traffic-sign recognition, rear automatic braking, a surround-view camera system, and front and rear parking sensors.

One caveat is that i-Activesense does not include a lane-centering function, which some competitors offer. That is not a dealbreaker for everyone, but it is worth knowing if you want the most advanced highway-assist setup.

Should I buy a 2021 Mazda MAZDA6 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:

• 27.0% of listings are priced as good or great deals.
• At 63.5% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.
• Price trend: Prices are up 1.38% year-over-year.
• Owners rate it 5/5 — a strong satisfaction signal.
• The 2021 Mazda6 stands out as a stylish, high-quality family-sized four-door that is especially rewarding to drive, even though it is one of the older members of its class.

The bottom line: The 2021 Mazda MAZDA6 is a smart pick if you want a midsize sedan that prioritizes style, driving enjoyment, and a premium feel over the newest tech. If you are price-sensitive, the best path is to focus on clean-history examples with strong equipment and compare them carefully against lower-mileage listings, because the market still offers some good deals but not a huge amount of inventory.
