2008 Mazda MX-5 2.0L Petrol · HD08 ONJ

The vehicle is currently roadworthy but the maintenance history reveals a worsening trend regarding structural corrosion and rubber degradation. While it passed the most recent test in April 2026 at 92,380 miles, the record shows a clear progression of defects related to the chassis and suspension components. The transition from a clean record in 2023 to multiple advisories and a failure in 2024 indicates that the vehicle is entering a phase where aging components require proactive replacement. At 18 years old, the Mazda MX-5 has covered a relatively low total of mileage, averaging approximately 5,132 miles per year. This low usage often correlates with the vehicle sitting for extended periods, which is supported by the recurring reports of perished and corroised tyre sidewalls. The mileage gap between 86,645 miles in April 2023 and 92,380 miles in April 2026 shows consistent use, but the low mileage has not prevented the natural degradation of rubber materials and the oxidation of metal surfaces. A buyer must conduct a thorough underbody inspection focusing on the front and rear subframes and inner sills. The tester consistently flagged corrosion in these areas across the 2024, 2025, and 2026 tests, and while currently described as not seriously weakened, rust on these models typically accelerates. The front anti-roll bar bushes and suspension arm pins have been noted as worn for three consecutive years, suggesting that the owner has deferred mechanical repairs despite repeated MOT advisories. Specific attention is also required for the braking system and shock absorbers. The nearside front brake failed for binding in 2024, and the rear shock absorbers showed oil misting in 2025. Given the history of perished tyres with deep cracking across multiple tests, the current set of tyres should be checked for deep structural cracking, regardless of the remaining tread depth.
