2015 Mazda 6 2.2L Diesel · CX65 OOJ

The 2015 Mazda 6 presents a stable roadworthiness trend with a clean pass at 79,975 miles in the September 2025 test, just under ten months before the current date. The vehicle carries no recorded defects across its recent MOT history, and the absence of advisories suggests the previous owner addressed consumables and mechanical items before each examination. This pattern indicates consistent, if not proactive, maintenance rather than deferred repair. Recorded mileage rose from 58,861 at the September 2023 failure to 79,975 by September 2025, an average of roughly 10,500 miles per year across that span against a lifetime mean near 7,270. The jump from 69,349 to 69,350 miles between the failed and passed tests on 18 September 2024 shows a one-mile retest correction, not real use. Sparse entries before 2023 leave earlier wear unknown, but the clean sheet from 2023 onward implies the car was not neglected in its later life. The September 2023 and September 2024 failures list no defects, pointing to administrative or presentational issues at the testing station rather than mechanical fault. Buyers should still commission an independent inspection of suspension bushes, coil springs, and brake disc thickness, as eleven years of age invites silent corrosion even without MOT flags. Verify underneath structural integrity for rust at sills and subframes given the low annual mileage may reflect periods of standing. Given the spotless advisory record, focus the viewing on tyre sidewall condition, wiper function, and a cold-start emissions check. The previous keeper clearly kept the Mazda to test standard; the risk lies in unseen wear the MOT never captured.
