1993 Mazda MX-5 1.8L Petrol · K671 EEP

Structural corrosion is the primary concern for this vehicle, with a history of rust-related advisories that have progressed into critical failures. The most recent test in July 2025 resulted in a failure due to inadequately repaired sills at the rear suspension mounting areas on both sides, alongside a leaking power steering pipe. This follows a pattern of structural warnings dating back to 2010, including corrosion at seat belt anchorages and subframe mountings, indicating a persistent and worsening issue with the vehicle's structural integrity. The recorded mileage of 137,321 miles is low for a thirty-three-year-old vehicle, averaging roughly 4,161 miles per year. However, the MOT history reveals a significant eight-year gap between August 2017 and July 2025. Such a prolonged period of inactivity often correlates with the degradation of rubber components and the acceleration of corrosion in stagnant areas, which is reflected in the recent failure of the power steering hose and the deterioration of the rear chassis members. A physical inspection must prioritise the quality of the repairs to the rear sills and suspension mounting points to ensure they meet DVSA standards for structural soundness. Particular attention should be paid to the front and rear subframes, as these were previously flagged for corrosion. During a test drive, listen for knocks or clunks over uneven surfaces that could indicate failing suspension bushes or ball joints, similar to the play previously noted in the front lower suspension arm. The braking system requires close scrutiny given the recurring history of corroded brake pipes and deteriorated hoses. Check the height of the handbrake lever, as little reserve travel has been a chronic advisory. Additionally, inspect the power steering system for active leaks and monitor the steering weight for consistency. Any judder during braking or a soft pedal should be investigated, considering the previous records of uneven brake application and efficiency failures.
