1994 Mazda MX-5 1.8L Petrol · M505 COR

A clear picture emerges from the MOT history of a 32 year old MX-5 with several structural corrosion advisories that warrant close attention, even though the car has continued to pass its annual tests. The most recent examination on 1 May 2026 initially recorded a failure for the offside parking brake being inoperative on one side, before a same-day re-test produced a pass. Across the visible record, the only outright failure is that parking brake issue, but a steady accumulation of advisories points to ongoing wear in familiar areas of an older MX-5. The rear sub-frame was flagged for corrosion in May 2026, the rear chassis/cab within 30cm of a mounting in April 2024, and the nearside rear inner sill structure as far back as May 2021. Corrosion of this nature is progressive on early Nineties Mazda chassis, so each of these items is best treated as a developing concern rather than a static observation. Mileage of 206,506 on a 1994 car equates to roughly 6,453 miles per year, which is broadly average for the age and platform, though the test record itself is far from continuous. The MOT history skips from 2016 to 2018, then to 2019, before gaps of around two years to 2021, two to three years to 2024, and a final gap to 2026. The absence of tests between 2016 and 2017 is unusual given annual testing would otherwise apply, and combined with the multi-year gaps, it suggests the vehicle has spent periods off the road or unregistered for use on the public road. For a 1.8 or 1.6 Mk1/Mk2 MX-5, that level of annual mileage, spread over three decades, will have placed significant cumulative demand on the suspension, braking system, rubber components, and the underside of the car, which is consistent with the wear pattern visible in the advisories. The advisories on the anti-roll bar linkage, rear sub-frame corrosion, and the April 2024 oil leak and corroded rear brake pipe collectively describe a chassis that needs a careful appraisal before purchase. The anti-roll bar linkage wear recorded in May 2026 is a known MX-5 issue; on a test drive listen for clonks or knocking from the front end over speed humps and during direction changes, and have someone rock the car side to side to feel for slack. The rear sub-frame and lower sill corrosion should be inspected on a ramp with the undertrays removed, paying particular attention to the rear sub-frame mounting points and the chassis legs behind the rear wheels, as the recorded advisories specifically mention these areas. Confirm the oil leak from 2024 has been resolved, and check the rear brake pipes for surface corrosion, kinks, or flaking, as pipe replacement is commonly needed on cars of this vintage. Brake-related attention should focus on the offside parking brake that failed in May 2026, verifying that the cable, lever mechanism, and rear caliper or drum actuator are now operating correctly, and confirming firm handbrake holding on an incline. The shock absorber oil misting recorded on both the offside front and nearside rear in 2016 should be rechecked for continued seepage and any deterioration in damping, as worn dampers can produce a floaty ride, uneven tyre wear, and front-end dive under braking. The recurring windscreen chip noted as a minor in 2019, 2021, 2024, and 2026 should be inspected for crack propagation, and the rear tyres showing edge wear in 2026 warrant a check of wheel alignment and rear suspension bushes, including the trailing arm bushes which are a known wear item on this generation. Given the age, the structural advisories, and the mileage, a pre-purchase inspection on a lift is strongly advisable.
