2007 Mazda MX5 2.0L Petrol · EY57 FNW

The vehicle remains roadworthy, but the maintenance history reveals a persistent trend of structural and mechanical degradation. While the most recent test in May 2026 at 87,854 miles passed, it carried forward recurring issues that were noted in previous years. The presence of corrosion on the rear suspension and coil springs, alongside an ongoing rear differential oil leak, indicates that while the car meets minimum safety standards, the underlying components are reaching a state of advanced decay that is not being proactively addressed or replaced. At 87,854 miles, this 19-year-old Mazda averages approximately 4,600 miles per year. The data shows consistent low-mile usage, with only 1,000 miles driven between July 2024 and July 2025. However, this low mileage often correlates with accelerated corrosion on older vehicles that sit stationary for long periods. The recurring reports of rust on the rear inner sills and suspension components suggest that the vehicle is suffering from environmental factors rather than mechanical wear from high-frequency road use. A buyer must conduct a thorough inspection of the rear inner sills and subframe, as rust has been a documented concern since at least 2025. The tester noted that the suspension components are not yet seriously weakened, but the repetitive nature of this advisory suggests structural integrity will require close monitoring. The rear brake discs are consistently pitted and scored across three years of testing, indicating a lack of replacement despite the visible deterioration. Additionally, the persistent differential oil leak should be monitored to ensure it does not evolve into a catastrophic failure of the rear assembly.
