2016 Mazda MX-5 2.0L Petrol · A26 SCC

The most recent DVSA examination on 13 May 2026 returned a PASS with no defects recorded, which is a positive outcome for a prospective buyer. However, the preceding test on 24 April 2026 resulted in a FAIL due to a major defect concerning an excessively binding offside rear service brake, alongside advisories for thin brake pads front and rear, pitted brake discs at both axles, localised structural corrosion within 30cm of a mounting point, and a slightly binding nearside rear brake. The fact that the vehicle passed shortly after this failure, just nineteen days later, suggests the binding brake and associated issues were rectified, although no advisories were carried over into the latest pass. Looking at the broader trend, the MOT record reveals a recurring pattern of brake-related advisories spanning from 2020 onwards, with brake disc pitting noted at every test since 2021 and pad wear flagged periodically. This indicates a steadily worsening rather than improving picture for the braking system, which warrants careful inspection even though the current pass is clean. The recorded mileage of 45,714 miles over a ten-year period equates to an annual usage of approximately 4,571 miles, which is well below average for a vehicle of this age. Such low mileage typically reflects either light recreational use or extended periods of standing, both common scenarios for an MX-5. While low mileage generally preserves engines and drivetrain components, it can accelerate deterioration of items that suffer from lack of use. The recurring brake disc pitting advisories across multiple tests are consistent with corrosion building up on discs that have seen limited regular driving, and the binding rear brake caliper recorded at the April 2026 failure is a classic symptom of a caliper piston or slider mechanism seizing after prolonged inactivity. Any prospective buyer should therefore view this low-mileage profile as a double-edged sword, where mechanical internals may be sound but brake and underbody components may have aged prematurely through standing. A thorough physical inspection should begin with the braking system, given the recurring advisories. The front and rear brake discs should be examined for lipping, corrosion ridges, and scoring, particularly around the outer edges and friction surfaces. Brake pad material should be measured for remaining thickness, and the offside rear caliper should be checked carefully for binding, seized sliders, or a sticking piston by ensuring the wheel rotates freely and evenly by hand when jacked. During a test drive, listen for any scraping, grinding, or rumbling noises from the brakes, and pay attention to brake pedal feel, watching for excessive travel, sponginess, or any pulling to one side under braking. A distinct shudder or vibration through the steering wheel or brake pedal may indicate warped or severely corroded discs that require machining or replacement, particularly after the vehicle has been standing in damp conditions. Beyond the braking system, several age-related items deserve close attention given the low annual mileage. Tyres should be inspected not just for tread depth but for sidewall cracking, perishing, and age-related degradation, as tyres older than six years can lose flexibility even with adequate tread, and an original 2016 production MX-5 may still be running its factory rubber. The 12V battery should be load-tested, as batteries that have been undercharged through infrequent use often fail without warning. Brake fluid, coolant, and engine oil should be checked for condition and service intervals, as these fluids degrade with calendar age regardless of mileage, and any lack of recent service history stamps should be treated as a negotiating point. Given the advisory for localised structural corrosion within 30cm of a mounting point, the underside should be examined on a ramp for any bubbling, flaking, or perforated metal, particularly around suspension and engine mounting areas. Finally, the soft-top roof, if fitted, should be checked for leaks, seam integrity, and hood frame corrosion, while the rear subframe and wheel arches, known corrosion hotspots on earlier MX-5s, should be inspected for any emerging rust that would compromise long-term structural integrity.
