2008 Mazda MX-5 1.8L Petrol · SA08 GJU

The vehicle remains roadworthy, but the maintenance trend shows a shift from minor consumable wear to structural concerns. While the most recent test on June 9 2026 at 52,457 miles passed, the tester identified new issues that were not present in previous years. The appearance of corrosion on the nearside and offside rear inner sills, alongside noted corrosion on both sub-frames, indicates that surface oxidation is actively progressing. Although these components are currently classified as not seriously weakened, they represent a transition from aesthetic to structural degradation that requires close monitoring. The mileage profile is exceptionally low for an 18-year-old vehicle, averaging approximately 2,914 miles per year. The data shows consistent, low-impact usage, moving from 45,213 miles in May 2022 to 52,457 miles in June 2026. This pattern suggests the car has not seen heavy mechanical stress from mileage, but it often correlates with the structural issues noted here. Vehicles left for long periods or driven infrequently are prone to accelerated corrosion due to a lack of airflow and moisture retention away from the chassis. A buyer must conduct a thorough physical inspection of the vehicle's underbody, specifically focusing on the inner sills and sub-frames. The recurring underbody corrosion noted since 2022 has culminated in specific sill defects in 2026 suggests a need to check for thinning metal or hidden structural rot. Additionally, the nearside front service brake binding recorded in the latest test indicates a sticking caliper or a seized piston, which is common in low-mileage cars where components sit stationary. The history of worn tyres in 2022 and 2023 also suggests the previous owner only replaced consumables when they reached the legal limit, so the buyer should verify the current condition of all rubber and suspension components.
