2020 MINI Cooper S 2.0L Petrol · WN20 AAJ

The vehicle passed its most recent MOT on 24 June 2026. The overall maintenance trend is generally stable, although there has been a slight increase in recorded advisories over the last two years compared to the clean reports of 2023 and 2024. While the car remains roadworthy, the emergence of specific wheel and tyre concerns suggests that the vehicle is now entering a period where age-related degradation and external impacts are becoming evident. With 28,404 miles recorded over approximately six years, the annual usage averages around 4,734 miles, which is significantly lower than the typical UK average. While this low mileage suggests minimal wear on the engine and drivetrain, it introduces specific risks associated with vehicle inactivity. Low-use vehicles are frequently susceptible to the perishing of rubber components, battery health decline, and the accumulation of corrosion on brake discs due to prolonged periods of standing. The MOT history highlights specific issues regarding the rear axle that require close scrutiny. The 2025 advisories for cracking and perishing on both rear tyres, coupled with the 2026 advisory for a distorted nearside rear wheel, indicate either a history of curb impact or degradation from lack of use. During a test drive, the buyer should be alert for any unusual vibrations or a rhythmic thumping sensation from the rear, which could signal a buckled rim. A physical inspection of the tyre sidewalls is essential to ensure they have not been replaced with inferior tyres or left to perish further. The most recent advisory regarding the coolant level being at the minimum is a point of concern that requires immediate verification. The buyer should determine if this was a simple maintenance oversight or if it indicates a slow leak within the cooling system, which is critical for the thermal management of the Cooper S engine. Given the low mileage, it is imperative to verify the service book for calendar-based maintenance rather than mileage-based intervals. This includes checking the date of the last brake fluid change and inspecting the brake calipers for binding, which can occur when a vehicle is not driven frequently.
