2006 Mazda 5 2.0L Petrol · WA06 FSX

The most recent MOT record for this 2006 Mazda 5 indicates a pass, but the overall maintenance trend reveals a significant and concerning history of structural degradation. While the vehicle has successfully cleared recent tests, the history shows a pattern of worsening corrosion that reached a critical failure point in 2021, where multiple major defects were recorded regarding excessive corrosion to the sills, inner arches, and subframe mounting points. Although the 2022 test suggests these issues were addressed or monitored to a level that no longer constitutes an immediate failure, the recurring advisories regarding corrosion on suspension component mountings and the subframe indicate that the vehicle's structural integrity is under constant threat from oxidation. The recorded mileage of 117,964 miles over approximately twenty years equates to an average of roughly 5,900 miles per year. This is considered low annual usage for a vehicle of this age, which can be a double-edged sword. While lower mileage generally implies less mechanical wear on the engine and drivetrain, it often correlates with longer periods of standing or short, infrequent trips. In this specific case, the low mileage may have contributed to the documented issues, as vehicles that sit for extended periods are more susceptible to moisture retention and accelerated corrosion on suspension components, brake discs, and the chassis, as evidenced by the extensive advisory history. A prospective buyer must exercise extreme caution regarding the documented corrosion history. During a test drive, pay close attention to the chassis and suspension for any signs of renewed structural weakness or movement. Listen for clunks, knocks, or creaks when driving over uneven surfaces, which could indicate that the previously noted corrosion on suspension mountings or the subframe is affecting the stability of the suspension geometry or the integrity of the bushes and joints. The 2022 failure for a leaking offside rear shock absorber suggests that damping components have been replaced recently, but you should verify if this was part of a wider suspension overhaul. Furthermore, the advisory regarding a minor exhaust leak should be checked for any increase in cabin noise or exhaust fumes, which could indicate further degradation of the exhaust system. Given the low annual mileage and the age of the vehicle, a thorough physical inspection is essential beyond the MOT certificate. Check the tyres thoroughly for sidewall cracking or perishing, as rubber degrades over time regardless of tread depth. Inspect the brake discs for heavy surface corrosion or pitting, which often occurs when a vehicle is not driven frequently enough to keep the surfaces clean. You should also verify the service history to ensure that time-based maintenance, such as fluid changes for the coolant, brake fluid, and oil, has been performed according to the calendar rather than just mileage. Finally, check the condition of the 12V battery and ensure the electrical systems are functioning correctly, as low-use vehicles often suffer from battery sulphation and electrical gremlins.
