2020 Mazda MX-5 100TH Anniversary Edition 2.0L Petrol · AM55 DWM

The most recent MOT, carried out on 26 September 2025, was passed but returned two advisories – the off‑side front tyre was noted as being worn close to the legal minimum tread depth and the off‑side rear suspension arm pin or bush showed wear, though not yet causing excessive movement. The preceding two tests in 2024 and 2023 were clean, indicating that the vehicle has generally been maintained to a satisfactory standard, but the emergence of wear items this year suggests a modest decline in consumable condition rather than a systemic fault. At six years old the MX‑5 has logged 34,003 miles, averaging just under 5,700 miles per annum. This is well below the typical UK average for a sports‑car of this age and points to either predominantly short‑haul use or periods of extended storage. Low annual mileage reduces cumulative wear on engine, transmission and chassis components, yet it also raises the possibility that the car may have spent significant time idle, which can promote battery sulphation, tyre rubber perishing and corrosion of brake components if not periodically driven. Prospective buyers should give the tyres immediate attention. The off‑side front tyre’s tread is approaching the 1.6 mm legal limit; even if the depth is still acceptable, uneven wear can indicate mis‑alignment or worn suspension geometry. A visual inspection of all four tyres for sidewall cracking, dry rot or age‑related hardening is advisable, and the front tyre should be replaced promptly, with the rear set evaluated for replacement if tread depth is similarly low. On a test drive, listen for any clunk or knock when applying the brakes or negotiating bumps, particularly from the rear off‑side suspension where the worn arm pin or bush may begin to develop play. A gentle push on the rear wheel at the rear off‑side corner should reveal any excessive movement; excessive looseness would merit a bush replacement before the next service. Given the vehicle’s age and modest usage, a thorough calendar‑based inspection is prudent. Verify the condition of the 12 V battery – a load test or a check of the electrolyte level (if applicable) will reveal any loss of capacity that can arise from long periods of inactivity. Inspect the brake discs for surface corrosion or scoring, especially on the rear where standing can cause rust that may lead to uneven pad wear or binding calipers. Confirm that the coolant, brake fluid and engine oil have been changed within the manufacturer’s recommended intervals, as fluids degrade over time even without high mileage. Finally, review the service book for regular oil changes, spark‑plug replacements and any recorded suspension work; a complete and up‑to‑date service history will give confidence that the MX‑5’s low‑mileage advantage has been matched by diligent upkeep.
