2007 Mazda MX-5 2.0L Petrol · KW07 TCK

This Mazda MX-5 holds a valid MOT pass dated 9 June 2026 at 80,913 miles, but the record reveals a persistent and concerning pattern of structural corrosion that a buyer must treat seriously. The vehicle failed its first attempt that same day due to a major rear exhaust leak preventing emissions testing, which was rectified for the pass. Critically, the corrosion advisories are not new. Since at least May 2024, testers have repeatedly flagged corrosion to the front sub-frame, rear sub-frame, front crossmember, and rear sub-frame mounting areas. While the corrosion has not yet been deemed to seriously weaken the structure, its presence across multiple prescribed areas over consecutive years indicates an ongoing, worsening trend rather than a stable condition. The 2025 failure for a loose driver's seat bolt also points to sporadic, basic maintenance oversights. The mileage profile is notably low for a 2007 vehicle, averaging roughly 4,259 miles per year. The record shows 79,352 miles in May 2024, 80,349 miles in May 2025, and 80,913 miles by June 2026, indicating consistent but very light annual use. This low mileage suggests the corrosion is less likely to be from sustained mechanical stress and more likely the result of long periods of standing or damp storage, which accelerates surface corrosion on sub-frames and mounting points. The mileage accumulation is steady, with no sudden jumps or gaps that would raise odometer concerns. A buyer must conduct a thorough physical inspection of the vehicle's underside, focusing on the structural integrity of the front and rear sub-frames, the front crossmember, and the rear sub-frame mounting points. The repeated advisories mean these areas require close scrutiny for deep pitting, flaking, or perforation that could worsen between tests. The suspension components, which were specifically flagged for corrosion in the most recent test, should be examined for weakened bushes, corroded coil springs, and compromised damper bodies. The exhaust system, which failed for a major leak in June 2026, needs checking for further corrosion or poor repairs, particularly around the rear section and joints. Beyond the corrosion, the loose seat bolt from the 2025 failure suggests other basic fasteners may not have been checked. Inspect seat rail fixings, seatbelt anchors, and steering column mounts for security. Given the recurring structural advisories, a professional underbody inspection is strongly recommended to assess whether the corrosion has progressed to a point where welding or component replacement will be required to maintain roadworthiness beyond the current certificate.
