2004 Mazda MX-5 1.6L Petrol · YX54 PDY

The most recent MOT test on July 23, 2024, confirms the vehicle failed without any recorded defects, a pattern that has persisted across all five tests since June 2022. This suggests the failures were administrative or procedural rather than mechanical, though the lack of defects does not imply the vehicle has been maintained beyond basic legal compliance. The most recent test occurred just over two years ago, which is beyond the standard one-year interval for cars over six years old. Given the vehicle’s age and mileage, this gap raises questions about whether critical components—such as suspension bushes, coil springs, or brake calipers—have been inspected or replaced despite their expected wear at this stage. The recorded mileage of 66,888 miles over 22 years equates to approximately 3,040 miles annually, a figure significantly lower than the average for a car of this age. The intervals between tests reveal no rapid mileage accumulation, with the most recent 1,206 miles logged over a year, followed by a 1,014-mile gap between the 2023 failures. This suggests the vehicle has spent extended periods stationary, which could accelerate issues like suspension degradation or corrosion in underbody components. The lack of advisories or defects in any test implies no urgent mechanical concerns were flagged, but the absence of maintenance records means wear on non-MOT-tested items—such as timing belt or drive shaft—cannot be confirmed. Given the failure history and the vehicle’s age, a buyer should prioritise an independent inspection of suspension components, particularly the rear bushes and coil springs, which are prone to dry rot and cracking after 20 years. The brakes, while not explicitly failed, should be checked for uneven wear or binding calipers, as high-mileage MX-5s often develop issues with rear brake binding. Structural integrity is also critical; the underbody and wheel arches should be examined for corrosion, especially around the sills and subframe, as prolonged stationary periods can exacerbate rust. Finally, the exhaust system and emissions should be verified, as catalytic converter efficiency degrades over time and may not have been tested thoroughly in past failures.
