2018 Mazda MX-5 1.5L Petrol · GM18 AFN

The 2018 Mazda MX-5 has maintained a clean MOT history since its most recent test on 29 July 2025, with no defects or advisories recorded at 61,105 miles. This suggests the vehicle has passed all mandatory roadworthiness checks consistently over the past two years, though the July 2022 test—just three days before its failure—was unusually close in mileage (44,766 vs. 44,768), implying either a rapid resubmission or a near-miss on a minor issue that was quickly rectified. The absence of recurring advisories or repeated failures indicates no obvious pattern of neglect, though the lack of advisories does not preclude hidden wear on components like suspension bushes or brake calipers, which are not always tested to failure. The mileage progression of approximately 7,600 miles annually aligns with typical usage for its age, with no prolonged periods of inactivity or excessive wear. The gap between the 2022 failure and subsequent pass (just four days later) is notable but not concerning, as it may reflect a minor oversight rather than a systemic issue. There are no red flags in the mileage pattern—no sudden spikes or prolonged stagnation—that would warrant suspicion of deferred maintenance or excessive stress on high-wear parts. Given the clean MOT record, a buyer should prioritise a thorough inspection of suspension components, particularly the rear bushes and coil springs, as these are common points of failure in this model and are not always captured in MOT testing. The brakes, while not failed, should be checked for uneven wear or binding calipers, as repeated minor issues could escalate. Corrosion around wheel arches and sills, particularly in the UK climate, should also be examined, as structural integrity is not always evident from an MOT pass alone. Finally, the exhaust system—often a source of advisory notes—should be inspected for leaks or excessive rust, even if no MOT failures were recorded. The lack of advisories does not guarantee these areas are flawless, so visual and functional checks are essential.
