1998 Mazda MX-5 1.8L Petrol · R765 AVR

The vehicle is currently roadworthy, but the maintenance history shows a worsening trend regarding structural integrity. While the most recent test in September 2025 at 79,603 miles passed, the tester flagged significant surface corrosion on both the front and rear sub-frames. This represents a progression from suspension arm corrosion noted in 2023 and 2024. Although these components are not yet deemed seriously weakened, the spread of rust across the chassis indicates active oxidation that requires close monitoring. At 28 years old, the recorded mileage of 79,603 miles is remarkably low, averaging approximately 2,843 miles per year. The data shows consistent, low-intensity usage, with only 3,655 miles driven between the October 2023 and September 2025 tests. This low mileage explains the relatively low wear on certain drivetrain components, but it often correlates with the mechanical issues observed, as rubber parts and metal surfaces sitting for long periods can accelerate perishing and corrosion compared to high-mileage driven vehicles. A buyer must prioritise a thorough physical inspection of the entire chassis and suspension assembly. The MOT record highlights recurring issues with these components, specifically the corrosion on the suspension arms and sub-frames which have appeared in three consecutive years. The buyer should check if the rust has transitioned from surface-level to structural thinning. Additionally, the 2025 advisory regarding perishing and cracking on the offside tyres suggests the rubber compound is reaching the end of its functional life regardless of tread depth, which is a common symptom of low-use, aged vehicles.
