1990 Mazda MX-5 1.8L Petrol · H637 DUF

The MOT history for this Mazda MX-5 reveals a pattern of reactive rather than proactive maintenance. In the most recent test in April 2026 at 225,172 miles, the vehicle passed after a failure just eleven days prior. That failure highlighted significant issues including high carbon monoxide emissions, an inoperative horn and windscreen washers, and poor parking brake efficiency. While these items were rectified for the pass, the tester still flagged three tyres worn close to the legal limit with uneven wear, along with a binding nearside front service brake. This suggests that basic consumables and safety components are only addressed when they directly cause a test failure. With 225,172 miles over 36 years, the vehicle has averaged approximately 6,250 miles per year, which is consistent with a classic roadster. However, the frequency of failures has increased recently. Between February 2025 and April 2026, the car failed three consecutive tests. Recurring issues include a persistent oil leak, a failing track rod end ball joint, and an exhaust leak. The oil leak specifically was noted as excessive in early 2025 but non-excessive by April 2026, indicating a fluctuating condition that requires close monitoring for engine-related degradation. A buyer should exercise caution regarding the suspension and braking systems. The record repeatedly mentions uneven tyre wear, fluctuating front brakes, and binding calipers, which often point to neglected alignment issues or worn-out suspension bushes and rubber components. The previous mention of a missing steering rack gaiter in 2020 is also a red flag for future steering damage if not properly replaced. Given the age and high mileage, a thorough physical inspection for structural corrosion on the sills and chassis is essential, as the MOT record does not detail the integrity of the body beyond visible failures.
