1991 Mazda MX-5 1.6L Petrol · J210 CET

The most recent DVSA MOT recorded on 24 March 2023 resulted in a Pass, following a Pass in February 2022 and a pair of Fail entries in early 2022 and early 2023. Although the failures did not list any specific defects, the pattern of a Pass after each failure suggests that any issues identified at the time of the failures were remedied promptly, and the vehicle is presently presenting a satisfactory road‑worthiness status. The absence of recorded defects on the latest Pass indicates that, at least at the time of testing, the principal safety items – lights, brakes, steering, suspension and emissions – were deemed compliant. At 211 577 miles the car has accumulated an average of roughly 6 000 miles per year over its 35‑year life, a usage rate that sits comfortably within the normal range for a classic roadster of this vintage. The mileage is not excessive, which may point to periods of light use or long spells of storage; however, prolonged standing can accelerate rubber and metal ageing, particularly in the tyre sidewalls, suspension bushings and corrosion‑prone chassis sections. The relatively modest annual mileage also means that wear items such as clutch plates, timing belt and brake discs may have been replaced at intervals dictated more by calendar age than by distance, a factor a buyer should verify. Given the clean MOT record but the vehicle’s age, a thorough visual and tactile inspection is essential. Examine the tyre tread depth and sidewall condition for cracking, dry rot or uneven wear that could indicate mis‑alignment or worn suspension components. Inspect the under‑body for rust, especially around the sills, rear bulkhead and suspension mounting points, and check the exhaust system for perforations or broken hangers. The 12‑volt battery should be tested for cranking amperage and electrolyte level, as batteries over 10 years old often suffer from sulphation even if they appear to hold a charge. Verify that all fluid reservoirs – engine oil, coolant, brake fluid and power‑steering fluid – have been changed within the manufacturer’s time‑based intervals, as fluid degradation can occur even with low mileage. On a test drive, listen for any clunk, squeak or groan from the front and rear suspension, which may betray worn bushings, deteriorated coil springs or a loose anti‑roll bar. Pay attention to steering feel; any play or vibration could signal worn rack bushings or a failing steering rack. Observe the brakes for shudder, pulsation or uneven pad wear, which can be caused by warped discs or sticking caliper pistons that often develop after long periods of inactivity. Finally, monitor the engine for rough idle, mis‑fires or loss of power, symptoms that could arise from an overdue timing‑belt replacement or degraded ignition components. Addressing these points will give a prospective buyer a realistic picture of the MX‑5’s mechanical health and the likely near‑term maintenance required to keep it road‑worthy.
