2005 Mazda 6 2.0L Petrol · EX05 DFZ

The vehicle most recently passed its MOT on 14 April 2026 with a small cluster of advisories and minors recorded against it, and a review of the prior four tests confirms a generally stable but progressively ageing maintenance picture. None of the advisories have escalated into failure items during the recorded history, and the same minor front windscreen stone chip has been consistently noted as not adversely affecting the driver's view. However, the appearance of corrosion advisories on both the front and rear sub-frames across 2022, 2025, and 2026, alongside the rear suspension component mounting area and the offside front shock absorber bush in the latest test, indicates a vehicle entering a phase where structural and suspension corrosion is becoming more apparent. The earlier advisories relating to front brake disc wear and pad thinning in 2024, combined with the suspension arm bush perishing noted in 2023, suggest that consumables and bushes are being flagged regularly and are likely to require attention in the near term. With recorded mileage of 108,289 miles over 21 years, this Mazda 6 has covered an average of roughly 5,157 miles per year, which is notably low for the vehicle's age and class. The MOT mileage gap between 2021 and 2022, and the broadly consistent year-on-year readings, suggest genuine low usage rather than any irregularities. From a mechanical standpoint, this annual mileage profile means that wear-related failures such as cambelt or clutch wear are unlikely to have been excessive, but the car has almost certainly spent extended periods standing or being used only for short journeys, which carries its own consequences. Standing use accelerates tyre sidewall perishing, brake disc surface corrosion, calliper slide seizure, and degradation of time-sensitive fluids such as brake fluid, coolant, and engine oil. A prospective buyer should pay close attention to the corrosion pattern flagged by the MOT station. With sub-frame corrosion advisories on both front and rear assemblies now appearing across multiple tests, it would be prudent to place the vehicle on a ramp to visually inspect the sub-frames, rear suspension mounting areas, and lower suspension arms for any progression towards structural weakening, paying particular attention to any through-section corrosion or distortion around mounting points. The offside front shock absorber bush and the perished shock absorber bush advisory noted in 2023 should prompt a road test to listen for suspension clonks over speed bumps and uneven surfaces, and to check for any vagueness in the steering or uneven front tyre wear. Brake pedal feel should be assessed for any sponginess or pulling to either side, as the front discs were flagged as worn in both 2024 and 2025, and any judder or vibration under braking would suggest the discs have now reached the point of requiring replacement. Beyond the recorded defects, the low annual mileage and the vehicle's age warrant a thorough inspection of items that degrade with time rather than use. The tyres should be examined closely for sidewall cracking, perishing, or age-related hardening regardless of tread depth, as low-mileage tyres often outlive their functional service life in terms of grip. The 12V battery is highly likely to be approaching the end of its useful life given the vehicle's calendar age and should be load-tested, while the brake fluid, coolant, and automatic or manual transmission fluid should be checked for service history evidence, as these typically require replacement on a time rather than mileage basis. The brake calipers and rear drums or discs should be inspected for corrosion and binding, as prolonged standing can cause the slider mechanisms to seize, leading to uneven pad wear and pulling under braking. Finally, verify the service book stamps to ensure oil and filter changes have been carried out at appropriate intervals, as low annual mileage can sometimes mask lapsed servicing, and confirm that the timing belt and water pump replacement history is documented given the engine's age and mileage.
