What should I look for when buying a used 2018 Mazda MAZDA6?

At 48.8% 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 thorough inspection of bodywork, tires, brakes, and any signs of uneven wear or prior repair. Because the model’s value proposition depends on getting the right example, condition matters a lot more than simply finding the lowest sticker price. If you’re considering a higher-trim car, make sure the added equipment is working properly and that the car’s premium features haven’t been neglected.

Key things to evaluate:

• Trim level: The Sport trim includes standard LED headlights, push-button start, an 8-inch infotainment touchscreen, blind-spot monitoring with rear cross-traffic alert, and a rear-view camera, while the Touring adds 19-inch wheels, keyless entry, a sunroof, auto wipers and high beams, heated front seats with driver power and faux leather. The Grand Touring Reserve adds a heated steering wheel, memory settings, real leather, rear-seat heat, front-seat ventilation, adaptive LED headlights, and a head-up display, while the Signature adds a digital cluster, front and rear parking sensors, a 360-degree camera, Nappa leather, microfiber faux suede, and real wood trim.
• Powertrain: The base engine is a naturally aspirated 2.5-liter four-cylinder with 187 hp and 186 lb-ft of torque, paired with a 6-speed manual on Sport or an optional 6-speed automatic. Higher trims add a turbocharged 2.5-liter engine with 250 hp and 310 lb-ft of torque, paired with a 6-speed automatic.
• Safety package: The base Sport trim comes standard with blind-spot monitoring with rear cross-traffic alert and a rear-view camera. The $625 i-Activesense package adds forward-collision warning with automatic emergency braking, adaptive cruise, and lane-departure warning with lane-keep assist.
• Infotainment: The car uses an 8-inch touchscreen with Mazda Connect, and smartphone integration arrives through Android Auto and Apple CarPlay. The available head-up display adds real-time traffic sign recognition and turn-by-turn guidance.
• Fuel efficiency: The base engine returns 26 city mpg and 35 highway mpg, while the turbocharged automatic setup returns 23 city mpg, 31 highway mpg, and 26 combined mpg.

Which 2018 Mazda MAZDA6 trim should I buy?

The 2018 Mazda MAZDA6 is offered in 4 trim levels: Sport, Touring, Grand Touring, Grand Touring Reserve.

Here's the short version:

• Sport: This is the entry point, but it still gives you a strong value mix with LED headlights, push-button start, an 8-inch touchscreen, blind-spot monitoring with rear cross-traffic alert, and a rear-view camera. If you want the lowest-cost way into the MAZDA6 and are comfortable with the simpler setup, this is the trim to start with.
• Touring: This trim adds the features many shoppers will actually feel day to day, including keyless entry, a sunroof, heated front seats, faux leather, and more convenience equipment. It’s the best-value choice for many buyers because it closes much of the gap to the higher trims without jumping all the way to luxury pricing.
• Grand Touring: This is the first trim with the turbocharged 2.5-liter engine, plus an upgraded infotainment system, 11-speaker stereo, navigation, and satellite radio. Choose this if you want the stronger performance character that helps define the upper end of the lineup.
• Grand Touring Reserve: This trim adds a heated steering wheel, memory settings, real leather, rear-seat heat, front-seat ventilation, adaptive LED headlights, and a head-up display. It makes sense if you want the most comfort-focused version short of the Signature.

The safety package is especially notable because the base trim already includes blind-spot monitoring with rear cross-traffic alert and a rear-view camera, while the available i-Activesense package adds forward-collision warning with automatic emergency braking, adaptive cruise, and lane-departure warning with lane-keep assist.

Is now a good time to buy a used 2018 Mazda MAZDA6?

This looks like a moderate, selective buyer’s market, so you can shop with some leverage if you’re patient and compare listings carefully.

• Deal availability: 33.3% of listings are priced as good or great deals.
• Inventory: There are 381 listings available.
• Price trend: Prices have softened 2.98% compared with last year.
• Clean inventory: 48.8% of listings are accident-free.

If you find a listing below $15,794, that's toward the low end of the year-round range and worth acting on quickly.

What is the 2018 Mazda MAZDA6's resale value?

The current average of $16,038 sits slightly below last year's $16,531.

That kind of softening suggests the market has become a bit more favorable for buyers, but it also means future sellers may need to price competitively to move a car quickly. If you buy well now and keep the car in strong condition, you’re better positioned to preserve value later. The model’s strong owner satisfaction should help support demand when it’s time to sell.

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 MAZDA6 safe?

The 2018 Mazda MAZDA6 earns five-star ratings in all NHTSA tests except rollover and front passenger side tests, which earned four-star ratings.

It earns an 8/10 safety score from our experts.

The base Sport trim comes standard with blind-spot monitoring with rear cross-traffic alert and a rear-view camera, and the available i-Activesense package adds forward-collision warning with automatic emergency braking, adaptive cruise, and lane-departure warning with lane-keep assist. That means you can get a strong safety feature set without moving far up the trim ladder.

One caveat is that the safety testing shows a couple of lower NHTSA results, so if safety is a top priority, you should pay close attention to the exact car’s equipment and condition.

Should I buy a 2018 Mazda MAZDA6 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:

• 33.3% of listings are priced as good or great deals.
• At 48.8% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.
• Price trend: Prices have softened 2.98% compared with last year.

The bottom line: The 2018 MAZDA6 is the right pick if you want the strongest blend of style, value, and premium feel in this generation. If you’re more price-sensitive, you can still shop carefully and focus on the best-maintained examples, but the 2018 stands out because of its redesign, added turbo power, and strong owner satisfaction.

How does the 2018 Mazda MAZDA6 compare to the 2018 Honda Accord?

Our experts score the 2018 Mazda MAZDA6 7.8/10 and the 2018 Honda Accord 8.2/10.

The Accord has the edge in overall expert score, stronger fuel economy, and a much larger pool of listings to shop from.
