2007 Mazda 6 2.0L Petrol · KJ57 ABU

A 19-year-old Mazda 6 carrying 131,550 miles presents a roadworthiness picture dominated by the braking system and minor lighting items, with the most recent test on 12 August 2026 passing but issuing five advisories that point to wear accumulating across both axles. The current pass is the fourth consecutive pass since the only failure, recorded at the August 2023 test, which was caused by a non-functioning offside headlamp on dipped beam together with an inoperative nearside registration plate lamp. Front brake pads were flagged as wearing thin at both the 2024 and 2025 tests, and the 2026 test escalates this concern with advisories on both front and rear brake discs showing pitting and scoring, alongside an offside front service brake that was binding. The pattern is one of progressive rather than acute deterioration: nothing has yet reached failure threshold, but the advisory list has broadened from a single component to multiple brake-related items across two consecutive tests, which is consistent with a high-mileage vehicle approaching the point at which consumables need replacement rather than monitoring. The recorded mileage of 131,550 miles over approximately 19 years equates to around 6,900 miles annually, which is broadly typical for a car of this age and consistent with a mix of urban and longer-distance use rather than long periods of standing or unusually heavy motorway accumulation. MOT coverage has been annual without significant gaps, allowing a continuous view of condition, and the mileage progression between tests is steady rather than exhibiting the sharp jumps or extended plateaus that would suggest clock irregularities, fleet changes, or periods off the road. This continuity means the advisories can be read as a genuine trend rather than a snapshot, and the gradual accumulation of brake-related items aligns with the wear expected at this mileage for components such as pads, discs, and caliper slide mechanisms. A prospective buyer should focus their physical inspection on the brake system first. With both front and rear discs flagged as pitted or scored and the offside front caliper reported as binding, the car should be test-driven from cold with attention to pedal feel, any tendency for the vehicle to pull to one side under braking, and the presence of a hot wheel or acrid smell after a few stops, all of which would indicate that the binding caliper has progressed beyond an advisory state. The front brake pads have been noted as wearing thin at two successive tests and were last assessed in mid 2025, so the remaining friction material should be physically inspected through the wheel, with any metal-on-metal noise, vibration through the pedal, or a visibly worn sensor wire treated as evidence that replacement is overdue. The discs themselves should be checked for a pronounced lip at the outer edge and for uneven run-out that would produce pedal judder or steering wheel vibration under firm braking. Beyond the braking system, the headlamp condition warrants close attention given the failure history. The offside headlamp ceased to function on dipped beam in 2023, and although the car passed its 2026 test, both front headlamp lenses are now recorded as carrying a product contamination that is not yet seriously reducing light output, so a night-time check is worthwhile to confirm that main beam, dipped beam, and indicators all operate reliably and that output has not deteriorated since the test. The nearside registration plate lamp should be verified as functional. On a test drive, listen for any clonks or knocks from the front suspension over uneven surfaces, as the binding brake can mask uneven tyre wear, and inspect the nearside front tyre inner shoulder for feathering that would confirm a geometry or component issue. Finally, request evidence of when the brake fluid was last renewed, as the binding caliper and scored discs together indicate the braking system has been working hard, and a fluid change would be a sensible precaution regardless of the test outcome.
