2015 Mazda 6 2.2L Diesel · LT15 CKN

The vehicle’s most recent MOT test on 2025-05-19—just over a year ago—confirmed full roadworthiness with no defects recorded at 149,934 miles. This represents a stable maintenance trend over the past two years, as all preceding tests between 2022 and 2024 also passed without fail, including a rare retest in May 2024 that cleared immediately. The absence of advisories or recurring faults suggests the vehicle has been subjected to consistent, if not rigorous, servicing. However, the lack of a test since May 2025 means the car has now exceeded its annual MOT due date by over two months, placing it in a legally vulnerable position until retested. The recorded mileage of 149,934 miles over approximately 11 years equates to an average of 13,630 miles annually, which is unusually high for a vehicle of this age. The gap between the 2022 test at 132,660 miles and the 2024 tests—just 2,054 miles in nearly two years—indicates a period of minimal use, followed by a sharp acceleration in mileage accumulation. This pattern could imply extended periods of storage or off-road use, which may have accelerated wear on components like suspension bushes, coil springs, and drivetrain seals. The rapid mileage jump from 134,713 miles in May 2024 to 149,934 miles by May 2025 (over 5,000 miles in a year) further suggests aggressive driving conditions, potentially stressing the chassis and braking systems. Given the vehicle’s age and mileage, a buyer should prioritise an in-person inspection of high-wear areas such as the suspension geometry—particularly the rear subframe and bushings—for signs of excessive play or corrosion, as these are common failure points in high-mileage Mazdas. The brakes, though never flagged in tests, warrant scrutiny for uneven wear or binding calipers, especially if the vehicle has been driven hard. Structural integrity should be checked for corrosion around wheel arches, sills, and the rear subframe, where salt and moisture accumulate over time. Additionally, the exhaust system should be examined for leaks or excessive rust, as these often develop silently between MOT intervals. The absence of advisories does not guarantee these components are intact, so visual and functional checks are essential.
