2009 Mazda MX-5 1.8L Petrol · DD57 AAD

The vehicle presents a concerning trend of structural degradation that has progressed from manageable to critical. While it passed its most recent test in August 2023 at 108,324 miles, this followed a significant failure just one day prior. That failure revealed serious structural weaknesses in the offside rear inner integral body structure and a seriously weakened rear sub-frame, which compromised structural rigidity. Although the car secured a pass after the offside front shock absorber was replaced, the presence of light corrosion throughout the underside indicates that the underlying oxidation is active rather than resolving. The mileage pattern is consistent with a springer-year-old vehicle, averaging approximately 6,372 miles per year. The record shows steady progression from 99,943 miles in August 2021 to 108,324 miles in August 2023. This low annual mileage suggests the car has not been subjected to heavy use, but it often correlates with accelerated corrosion on older vehicles that sit stationary for long periods. The lack of recorded data since August 2023 means the vehicle is currently operating on its MOT expiry relative to the current date. A buyer must prioritise a thorough physical inspection of the chassis and mounting points. The history shows recurring issues with the front and rear sub-frames and suspension mounting areas, which transitioned from corroded to seriously weakened between 2022 and 2023. The repaired nearside rear inner structure must be scrutinized to ensure the weld is sound and free from spread. Furthermore, the previous failures involving a fractured coil spring, leaking shocks, and binding rear brakes suggest the suspension and braking components are reaching the end of their functional life and require close monitoring for further failure.
