1997 Mazda MX-5 1.6L Petrol · P690 CFT

The most recent MOT test for this 1997 Mazda MX-5 was passed on 18 November 2025, following a failure six days prior due to a non-functional horn. While the vehicle has successfully cleared its most recent inspection, the maintenance trend indicates a persistent and worsening issue with structural corrosion. The history shows a recurring pattern of advisories regarding both the front and rear sub-frames, which have been noted consistently since at least 2023. Although these are currently classified as not seriously weakened, the repeated mention of corrosion across multiple years suggests a progressive degradation of the chassis that requires close monitoring to prevent future structural failure. With a recorded mileage of 115,056 over approximately 29 years, this vehicle has averaged roughly 3,967 miles per year. This is significantly lower than the UK average, suggesting the car has been used primarily for leisure or has spent considerable periods stationary. While low mileage often implies less mechanical wear on the engine and drivetrain, it can present specific risks for a vehicle of this age. Long periods of standing can lead to the degradation of rubber components, the drying out of seals, and the accumulation of moisture in hard-to-reach areas, which likely contributes to the significant corrosion noted in the MOT history. A prospective buyer must prioritize a thorough inspection of the vehicle's underside, specifically focusing on the sub-frames and suspension mounting points. The advisory regarding the nearside front upper suspension arm ball joint dust cover being severely deteriorated is a concern; if the boot splits further, grit will enter the joint, leading to premature wear and knocking sounds during low-speed maneuvering or over bumps. Furthermore, the history of corroded and fractured coil springs indicates that the suspension system is nearing the end of its serviceable life. During a test drive, listen for any metallic clunks, creaks, or uneven handling, which could signal that the previously advisory corrosion on the suspension arms or springs has progressed into a mechanical defect. Given the low annual mileage and the age of the vehicle, additional attention should be paid to age-related degradation that occurs regardless of distance travelled. Inspect the tyre sidewalls for signs of perishing or cracking, as rubber loses its elasticity over time even if tread depth remains high. Check the brake discs for heavy surface corrosion or binding calipers, which are common in vehicles that sit idle. It is also essential to verify the service history to ensure that fluids, such as brake fluid and coolant, have been changed on a calendar basis rather than just by mileage, as these fluids absorb moisture over time and can exacerbate the internal corrosion seen in the sub-frames and suspension components.
