Mazda 6 Review Is This Stylish Saloon the Smartest Used Car Buy

Why Consider a Mazda 6 Over the Usual Executive Saloons?

When most people think about executive saloons, the big German names—BMW, Audi, Mercedes-Benz—tend to dominate the conversation. But what if you’re after something that stands out from the crowd, without sacrificing practicality, efficiency, or that all-important sense of style? Enter the third-generation Mazda 6. It’s a car that’s quietly carved out its own niche, offering a refreshing alternative for drivers who want more than just a status symbol on their driveway.

What Sets the Mazda 6 Apart in Terms of Efficiency and Running Costs?

Mazda’s approach with the Mk3 6 was all about clever engineering. Their Skyactiv technology isn’t just a marketing buzzword—it’s a suite of innovations designed to squeeze more from every drop of fuel. Both the petrol and diesel engines share a high 14:1 compression ratio, which is unusually efficient for this class. The result? Up to 15% better fuel economy compared to previous generations, and lower CO2 emissions to boot.

If you’re clocking up miles on the motorway, the 2.2-litre diesel engines (offered in 148bhp and 173bhp variants) are the sweet spot. Real-world drivers regularly report 45mpg in mixed driving, with 55mpg not out of reach on longer, steady runs. Opt for the manual gearbox and you’ll not only enjoy a more engaging drive, but also benefit from road tax as low as £35 per year—a rare treat in this segment.

How Does the Mazda 6 Drive Compared to Its Rivals?

Here’s where the Mazda 6 really shines. While the Ford Mondeo and Volkswagen Passat are often praised for their comfort, the Mazda 6 brings a sense of agility and driver engagement that’s hard to match. The steering is precise, the chassis feels nimble, and body roll is kept nicely in check. It’s the kind of car that actually makes you look forward to a winding B-road, not just tolerate it.

That said, it’s not all roses. At lower speeds, the suspension can feel a bit firm, especially over potholes or sharp bumps. But on the open road, the 6 settles down beautifully, making it a relaxed cruiser for long journeys.

What Are the Practicalities—Boot Space, Family Use, and Everyday Comfort?

Saloon or estate? That’s the big question. The saloon offers a generous 480-litre boot—plenty for a family holiday or a couple of golf bags. But if you’re regularly hauling pushchairs, bikes, or the assorted gear that comes with a busy family life, the estate version is a no-brainer. With the rear seats folded, you get a cavernous 1648 litres of space. That’s up there with the best in class.

Inside, the Mazda 6 is generally well thought out. Early models had a few rough edges in terms of material quality, but the 2015 facelift brought a noticeable step up—softer plastics, a neater 7-inch infotainment screen, and a more premium feel throughout. Later models (from 2018 onwards) even introduced a 2.5-litre petrol engine, though these are rare and don’t add much in the way of extra performance.

How Much Should You Budget for a Used Mazda 6?

One of the Mazda 6’s biggest draws is its value for money. Early, high-mileage examples can be found for under £2,000, but these will likely have seen well over 100,000 miles. If you’re after something tidier, with a good service history and fewer miles, a budget of around £6,000 should net you a solid saloon or estate from the post-2015 facelift era. If you want the latest shape and features, expect to pay closer to £9,000 for a 2018-onwards model.

Are There Any Common Issues or Things to Watch Out For?

No car is perfect, and the Mazda 6 is no exception. Early models can suffer from interior wear and tear, and some owners have reported issues with diesel particulate filters (DPF) on cars used mainly for short journeys. As with any used car, a full service history is essential, and it’s wise to check for any signs of neglect or skipped maintenance. The good news? Mazda’s reputation for reliability is strong, and most owners report few major headaches.

What’s the Real-World Ownership Experience Like?

Talk to Mazda 6 owners and a few themes crop up again and again: understated style, rewarding drive, and low running costs. It’s a car that doesn’t shout about its credentials, but quietly gets on with the job—whether that’s a daily commute, a family road trip, or the occasional spirited drive. And thanks to its distinctive looks, it still turns heads even a decade after launch.

The big takeaway? Choosing a Mazda 6 isn’t about perfection—it’s about smarter adjustments. Start with one change this week, and you’ll likely spot the difference by month’s end.
