Insight summary

Mazda 6 is a scarce model in this snapshot, with 49,730 represented vehicles and 0.12% of the active UK pool tracked by AutoRank. For the last 5 years, it has a pass rate of 76.2% from 412,502 MOT tests, with a reliability score of 48. The current pool shows an average of 106,200 miles and an average age of 12.2 years, while mature-fleet mileage is estimated at 114,678 miles. Diesel leads the fuel split, followed by petrol, and the most frequent defect themes are parking brake, lighting and windscreen damage. The practical read is that the Mazda 6 looks like a solid used-car baseline rather than a rare find, with age, mileage and common wear items doing most of the explaining.
