2007 Mazda 6 2.0L Diesel · DV57 WTP

The vehicle history shows a clear trend of accelerating mechanical degradation, particularly regarding the suspension and chassis. In the most recent test in August 2025 at 130,233 miles, the car failed on an extensive list of faults including worn front suspension arm bushes, perished ball joint dust covers, and heavily corroded exhaust joins. Crucially, the tester also identified significant corrosion on the rear sub-frame and rear suspension arms. While these were noted as not yet seriously weakened, the recurring presence of rust across multiple underbody components suggests the structural integrity of the vehicle is reaching a stage where corrosion will require constant monitoring. With 130,233 miles recorded over 19 years, the car averages approximately 6,850 miles per year. This low mileage is consistent with typical domestic use, yet the record indicates that basic maintenance has been reactive rather than preventative. Between August 2023 and August 2025, the vehicle failed its annual inspections multiple times with recurring issues such as worn pads, thin discs, and suspension play. The failure in 2024 regarding an offside front upper suspension arm ball joint likely to detach would have necessitate immediate repair to maintain road safety. The mechanical profile reveals a pattern of neglected consumables and wear-related components. The braking system frequently appears flagged for thin pads and pitted discs across several years, while the suspension remains a constant concern due to failing bushes and joints. The 2025 failure also highlighted defective headlamp lenses and a perished tyre sidewall, indicating that minor safety-critical items are often overlooked. A prospective buyer should account for significant upcoming expenditure to address the spreading underbody corrosion and the overhaul of the front and rear suspension geometry.
