2007 Mazda MX-5 2.0L Petrol · WF57 KHZ

The vehicle is currently roadworthy, but the maintenance history reveals a concerning trend of structural degradation. While the most recent test in November 2025 at 139,159 miles passed, the record shows persistent issues with corrosion on both the front and rear sub-frames. This structural weakness was flagged consistently across 2024 and 2025, indicating that while the rust has not yet reached the point of immediate failure, the chassis is in a state of ongoing advanced decay. At 139,159 miles over 19 years, the car has averaged approximately 7,300 miles per year, which aligns with typical annual usage for its age. The data shows consistent movement between tests, such as the 5,450 miles driven between November 2023 and November 2024, and another 5,747 miles between late 2024 and late 2025. This regular use suggests the vehicle is not sitting stationary, which helps prevent mechanical seizure but does not halt environmental corrosion. A buyer must conduct a thorough physical inspection of the sills and sub-frames. The November 2024 failure specifically highlighted the offside rear inner suspension mounting area as excessively corroded with significantly reduced structural strength. This is a critical failure point for an MX-5, as rust here often spreads to the main body sills. The buyer should also verify that the engine management light issue reported in the 2024 failure has been properly rectified, as an inoperative MIL can mask serious engine faults or emission failures.
