2017 Mazda MX-5 1.5L Petrol · WJ17 DYY

The vehicle remains roadworthy, though the maintenance trend shows a developing issue with the rear braking system. The most recent test in February 2026 at 21,712 miles flagged the rear brake discs as being pitted and scored. This follows a recurring advisory from the February 2025 test at 19,929 miles, where the tester noted pitting specifically on the inner surfaces. While the car passed these tests, the persistence of surface corrosion indicates the components are reaching their functional limit. The mileage profile is exceptionally low for a nine-year-old vehicle, averaging approximately 2,412 miles per year. The data shows consistent, low-interval usage, moving from 15,369 miles in early 2022 to 21,712 miles in early 2026. This level of use often suggests less wear on the drivetrain and engine components, but it frequently correlates with the issues seen in the braking system, as vehicles that sit for long periods are prone to surface rust on unpainted ironwork components like brake discs. A buyer should prioritise inspecting the rear brake calipers and discs to determine if the pitting has progressed to a point requiring immediate replacement. The 2023 record noted both rear tyres were worn to the legal limit and on the edge, which suggests potential alignment issues or uneven wear from long periods of inactivity. Given the low mileage, it is also vital to check for rubber rot on the tyres and any structural corrosion in the sills and wheel arches, as these are common vulnerabilities for low-mileage roadsters of this age.
