2015 Mazda 6 2.2L Diesel · LT15 RYK

The Mazda 6 presents a clean MOT history over the past year, with the most recent test in September 2025 at 117,851 miles passing without any defects. This follows a brief but uneventful anomaly in September 2024, where the vehicle failed a test at 108,774 miles before passing immediately afterward at 108,781 miles—a mileage difference of just seven miles. The lack of recurring advisories or defects in the last three tests suggests the car has been well maintained in critical areas, with no signs of worsening mechanical or structural issues. The absence of corrosion-related failures or brake/suspension advisories further supports a stable condition, though the single failed test without recorded defects is unusual and may warrant clarification from the seller. The mileage accumulation aligns closely with typical usage for a vehicle of this age, averaging around 10,714 miles per year over its lifetime. There are no red flags in the spacing between tests—gaps of roughly 12 months between 2023 and 2025 indicate regular MOT compliance, while the January 2022 test at 92,570 miles suggests a slightly longer interval (nearly 19 months) before the next check. This pattern does not imply neglect, but the buyer should verify if the car has been driven consistently or stood idle for extended periods, as lower-than-average mileage can sometimes mask deferred maintenance on components like coil springs, suspension bushes, or exhaust systems. Given the absence of defects in recent tests, the buyer’s primary focus should be on components not routinely checked in MOTs but prone to wear at this mileage. Inspect the suspension for worn bushes, degraded coil springs, or uneven tyre wear, which could indicate alignment or steering issues. Check brake binding or uneven pad wear, particularly if the car has been driven lightly—some owners defer brake work until symptoms appear. Structural integrity remains a key concern; look for corrosion in wheel arches, sills, or underbody panels, especially if the car has been garaged in damp conditions. The exhaust system should also be examined for leaks or rust, as emissions tests are not part of the MOT but could affect future passes. While the MOT history is reassuring, the buyer should treat the unexplained failed test as a minor anomaly and probe the seller for details—whether it was a tester error, a minor issue resolved before retesting, or an oversight. A pre-purchase inspection by a qualified mechanic would be prudent to confirm the car’s condition beyond the MOT’s scope, particularly given its age and mileage. The lack of advisories does not eliminate the need for due diligence on wear items and hidden corrosion.
