2007 Mazda 6 2.0L Petrol · FD57 DMZ

The most recent MOT test on the 2007 Mazda 6 was conducted on 2023-06-12 and resulted in a pass, though it followed a failed test in 2022-06-28, which also carried identical advisories regarding structural corrosion in the integral body, front and rear sub-frames, and minor windscreen damage. The pattern of repeated advisories on corrosion—particularly in the sub-frames and body structure—suggests a persistent but not immediately critical issue, as the tests consistently note that structural rigidity remains unaffected. The failure in 2020-06-30 due to a dangerously inefficient parking brake and the 2019-07-01 failures highlighting worn brake pads and binding calipers indicate past mechanical concerns that have either been addressed or are now less acute. Overall, the maintenance trend appears stable, with recurring advisories reflecting ongoing wear rather than sudden deterioration, though the brake-related failures in 2019 and 2020 underscore the importance of addressing those issues promptly to prevent further degradation. The vehicle’s recorded mileage of 146,248 miles over approximately 19 years represents an average of around 7,697 miles per year, which is consistent with typical usage patterns for its age. This rate does not suggest excessive wear from high annual mileage alone, but it does imply the car has been in regular service rather than standing idle for extended periods. The absence of significant gaps between MOT tests—particularly the lack of a 2021 MOT between the 2020 failures and the 2021 advisory—could indicate either routine maintenance intervals or a history of consistent use. However, the combination of low mileage and repeated structural advisories suggests the vehicle may have spent time in storage, where corrosion from moisture exposure becomes a far more insidious threat than wear from driving. This is particularly critical for sub-frames and body panels, which are prone to galvanic corrosion when left unattended. Given the recurring advisories on structural corrosion in the sub-frames and body, the buyer should conduct a thorough visual inspection for signs of rust progression, focusing on the lower sills, wheel arches, and areas beneath the vehicle where moisture can pool. Pay particular attention to the front and rear sub-frames, as these are critical load-bearing components; any visible pitting or flaking could indicate advancing corrosion that may compromise structural integrity over time. On a test drive, listen for unusual noises from the suspension, particularly clunks or rattles when driving over bumps, which may signal weakened or corroded suspension bushes or springs. Additionally, check for uneven tyre wear patterns, which could indicate misalignment or binding caused by corroded or binding calipers, as noted in the 2019 MOT failure. For brake systems, the buyer should verify the condition of the front and rear brake pads, discs, and hoses. The 2019 and 2020 MOT failures highlight significant wear on pads and discs, with some binding observed on the offside front service brake. Inspect the brake discs for scoring, warping, or excessive glazing, and measure the remaining pad thickness—if any pads are below 1.5 mm, they must be replaced immediately. Listen for grinding noises when applying the brakes, which could signal metal-to-metal contact from worn pads or warped discs. The front brake hoses, noted for slight corrosion in previous tests, should be checked for leaks or cracks, as brake fluid degradation can lead to reduced braking efficiency. Finally, given the vehicle’s age and the potential for standing corrosion, the buyer should also test the parking brake system to ensure it engages fully and securely, as the 2020 failure indicates a dangerous inefficiency that could pose a safety risk. Additionally, check the 12V battery and starter motor for signs of failure, as older vehicles are more susceptible to electrical issues from prolonged inactivity. For fluids, consider having the engine oil, brake fluid, and coolant serviced according to the manufacturer’s recommendations, as these can degrade over time even with moderate mileage.
