1992 Mazda MX-5 1.6L Petrol · K358 EEP

The vehicle presents a stable but aging profile, with the most recent MOT on 20 August 2025 at 93,579 miles showing a pass despite ongoing corrosion. While the vehicle has avoided outright failures in recent years, the record reveals a persistent, long-term pattern of structural and mechanical degradation. The maintenance trend suggests a reactive approach to repairs rather than preventative upkeep, as many issues flagged in previous years continue to reappear in different forms. The mileage history indicates very low usage for a 34-year-old vehicle, averaging roughly 2,752 miles per year. A significant period of inactivity is evident between the April 2019 test at 80,686 miles and the June 2016 test, though the data shows the car has consistently remained under the 100,000-mile mark. This low annual mileage often correlates with the type of corrosion seen here, as vehicles that sit for extended periods are prone to moisture retention and surface oxidation. A prospective buyer must prioritize a thorough underside inspection, specifically focusing on the rear subframe and suspension arms. The record shows a chronic issue with subframe and suspension arm corrosion dating back to at least 2021, with the 2023 test specifically noting corrosion on both rear suspension arms. Although the tester has consistently classified this as not seriously weakened, the recurring nature of these advisories suggests the structural integrity of the chassis is under constant threat from progressive oxidation. The braking system and hydraulic lines also require immediate attention. The vehicle has a history of leaking brake pipes, binding brakes, and master cylinder mounting corrosion, including a significant failure in September 2020 due to insufficient pedal travel and multiple leaks. While the 2025 test shows the master cylinder mounting corrosion is not excessive, the cumulative history of pitted discs, corroded pipes, and binding calipers indicates that the hydraulic and mechanical braking components are nearing the end of their reliable service life.
