2012 Mazda MX-5 1.8L Petrol · FN12 ATK

A 2012 Mazda MX-5 carrying just over 51,000 miles presents an MOT history dominated by clean passes, but the single failure in 2021 carries meaningful mechanical weight and warrants close scrutiny. The vehicle has now strung together five consecutive passes since that failure, with the most recent test on 28 January 2026 recording no advisories, suggesting that the immediate braking and suspension concerns were addressed at the time. However, the failure was not a minor one: an offside front brake pad worn down to its indicator, a leaking offside front shock absorber, and a brake fluid warning lamp illuminate simultaneously point to a front corner that had been neglected, or at least had reached a service threshold without intervention. The 2025 advisory for perishing on all four tyres is a separate ageing concern that has since been resolved but hints at a vehicle that may sit for stretches between uses, allowing rubber components to deteriorate even with low overall mileage. With 51,149 recorded miles spread across roughly fourteen years, the annual accumulation is around 3,650 miles, which is notably below typical mileage for any road car and particularly low for an MX-5, a model often bought specifically to be enjoyed. The MOT record shows consistent annual testing from 2019 onwards with no extended lay-up gaps, so the low figure does not appear to be the result of the vehicle being unlicensed or off the road for multi-year stretches. Mechanically, low annual mileage reduces wear on internal drivetrain components but raises the probability of dried rubber, oxidised brake fluid, seized calipers from infrequent use, and corrosion in areas that do not dry out through regular operation. The 2019 advisories for front and rear tyres worn close to the legal limit, combined with the 2025 perishing advisory across all four tyres, reinforce the impression of a car that covers short, infrequent journeys where tyres age faster than they wear. For a prospective buyer, the priority inspection points are the front brake and suspension components flagged in the 2021 failure. The offside front shock absorber should be checked for seepage around the body and top mount, and the car should be pushed laterally at each front corner to detect worn top mounts or bushes that have hardened with age and underuse. Brake feel on test is critical: any sponginess, excessive travel, or pulling under firm pedal application may indicate corroded caliper slide pins seizing on the offside, which is a common consequence of low-mileage cars where the brakes are rarely worked hard. The brake fluid itself should be tested for moisture content, as the warning lamp illuminated in 2021 can also be triggered by contaminated fluid, and a fluid change is advisable on age grounds regardless of warning lamp status. The tyre condition history also deserves a physical inspection beyond what the MOT records capture. Examine the sidewalls closely for any remaining cracking or perishing, particularly in the shoulder area, and confirm that all four tyres are of matching age and brand, as mixing of old perished rubber with new tyres is common on low-use vehicles. On the road, listen for any clonking or knocking from the front suspension over bumps, which could indicate worn drop links, anti-roll bar bushes, or bottom arm bushes that have hardened and cracked. Finally, given the cumulative low usage, check for any corrosion on the underbody, around the rear subframe mounting points, and on the brake discs themselves; a heavily corroded or pitted disc face, even with adequate thickness remaining, will produce judder under braking and is a typical finding on low-mileage MX-5s that have spent time parked outdoors.
