The vehicle holds a valid MOT certificate following the September 2025 test at 23,600 miles, though the maintenance trend reveals a persistent issue with the nearside front tyre. A recurring advisory for a cut not reaching the ply or cords appeared in August 2024 and again in September 2025. This pattern suggests repeated kerbing damage or a slow puncture rather than a manufacturing defect, pointing to a previous owner who frequently misjudges nearside proximity to kerbs. The offside front tyre failed on exposed cords in August 2024 but passed three days later, indicating a replacement was fitted and resolving that specific structural risk. The recorded mileage of 23,600 miles equates to a low annual average of roughly 4,720 miles, confirming light overall use. However, the interval between the August 2024 test at 11,148 miles and the September 2025 test at 23,600 miles shows a rapid accumulation of 12,452 miles in just over a year. This spike suggests the vehicle transitioned from a period of dormancy to regular, sustained use. Such a pattern can lead to dried-out suspension bushes and stressed drivetrain components from prolonged standing, despite the low total mileage. A physical inspection must prioritise the nearside front wheel and suspension geometry. Repeated tyre sidewall damage often results from aggressive kerb strikes, which can knock the wheel out of alignment and stress suspension bushes or track rod ends. Check the condition of the brake discs and calipers; vehicles standing for extended periods frequently suffer from surface corrosion on discs and binding calipers. Examine the exhaust system and underbody for corrosion, as the low mileage and short-journey profile typical of this usage pattern often prevent the exhaust from reaching optimal operating temperature to burn off moisture.
