2009 Mazda 3 1.6L Petrol · SL09 KOJ

The most recent MOT test on this 2009 Mazda 3, conducted on 21 October 2022 at 138,795 miles, resulted in a pass with no recorded defects. However, the preceding test on 20 October 2022—conducted on the same mileage—was a failure with no defects noted, suggesting a potential administrative or procedural anomaly rather than a mechanical issue. The pattern of testing remains consistent over the past three years, with no evidence of worsening faults or unresolved advisories. That said, the lack of defects in both the 2021 and 2022 tests does not preclude underlying wear, particularly in high-mileage components like suspension bushes, coil springs, or brake calipers, which often fail silently before MOT thresholds are triggered. The recorded mileage of 138,795 miles over approximately 17 years equates to an average of around 8,164 miles per year, which is typical for a vehicle of this age. There are no significant gaps or abrupt jumps in mileage between tests, indicating steady usage without prolonged periods of neglect or rapid depreciation. The most notable observation is the identical mileage at both the 2021 and 2022 tests, suggesting the vehicle may have been stationary for an extended period before resuming use. This could imply deferred maintenance or reduced activity, potentially allowing minor corrosion or fluid degradation to develop undetected. Given the lack of specific failures in the MOT history, a buyer should prioritise an independent inspection of suspension components, particularly the rear bushes and coil springs, which are prone to fatigue at this mileage. The brakes—though not explicitly failed—should be scrutinised for uneven wear, binding calipers, or corrosion on the discs and pads, as these are common failure points in older vehicles. Additionally, the subframe and wheel arches should be examined for signs of structural corrosion, especially if the car has spent time in wet or salted environments. Tyre condition, despite not being flagged in tests, warrants verification, as failing twice on tread depth in prior records suggests basic upkeep may have been inconsistent. Finally, fluid levels and condition—brakes, power steering, and coolant—should be checked, as prolonged inactivity can lead to degradation.
