Mazda 6 (GJ facelift)
The 2015-refreshed Mazda 6 (GJ) facelift brought a smarter cabin with MZD Connect infotainment and revised styling, but it still shares the same diesel caveats as earlier GJ models. In the UK, it remains a stylish and engaging alternative to the Volkswagen Passat and Ford Mondeo, with sharp handling and a premium-feeling interior that belies its mainstream price. Petrol cars—particularly the 2.0-litre SkyActiv-G—are the genuinely appealing used buy here, offering bulletproof reliability and linear performance without the DPF and oil-dilution risks of the 2.2-litre SkyActiv-D diesel. Insurance groups are competitive for the class, and Mazda's dealer network in the UK is well-established with reasonable servicing costs. The 2015 facelift also introduced improved sound insulation and updated interior materials, making later GJ models a noticeably more refined place to sit on long motorway journeys. For buyers seeking a large family car that is genuinely enjoyable to drive, the petrol-powered Mazda 6 facelift is a quietly excellent choice.
