2005 Mazda MX-5 2.0L Petrol · NV55 EWK

The vehicle presents a concerning structural profile that shows a worsening trend in corrosion despite passing recent tests. While the most recent MOT in November 2022 at 112,935 miles passed, the tester noted corrosion on all four inner suspension component mounting areas. This represents a progression from the 2019 failure, where the rear mounting points were flagged as being excessively corroded to the point of significantly reducing structural strength. Although the vehicle has remained roadworthy since that period, the underlying metal degradation of the chassis and mounting points appears active rather than resolving. The mileage history is consistently low for a 21-year-old vehicle, averaging approximately 5,378 miles per year. There is a significant gap in records between November 2022 and the present date of July 2026, with no recorded test data for nearly three and a half years. Between 2018 and 2022, the car covered only 15,827 miles over four years. This low usage suggests the car may have sat stationary for long periods, which likely could have accelerated the oxidation process on the subframes and sills noted throughout the inspection history. A buyer must prioritise a thorough structural inspection of the underside, specifically the subframes and chassis rails. The record shows a history of extensive rusting on the front and rear subframes, as well as the boot floor. Attention should be paid to the rear suspension mounting points and the seat belt anchorages, which previously failed for structural integrity issues in 2018. The braking system has also shown recurring issues with imbalance and worn components, particularly in late 2018 and 2019, requiring a check of the caliper operation and disc condition to ensure they have not seized or degraded during periods of inactivity.
