2021 MINI Cooper S Electric Level 2 Electric · LB21 KMF

The vehicle presents a stable and highly favorable maintenance trend, culminating in a clean pass at its most recent MOT on 3 March 2026. At 30,876 miles, the tester recorded zero defects or advisories, confirming the electric drivetrain and mechanical components meet current roadworthiness standards. An anomaly exists on the same date, showing a failed test at the identical mileage with no recorded defects, which typically indicates an administrative error or an aborted test rather than a mechanical failure. Regardless, the subsequent clean pass confirms the car left the test lane in a compliant state. The mileage accumulation aligns closely with typical usage for a five-year-old vehicle, averaging roughly 6,175 miles annually. Between the February 2024 test at 27,300 miles and the March 2025 test at 29,865 miles, the car covered 2,565 miles over a twelve-month period. The mileage then plateaued, showing just 1,011 miles of accumulation between the March 2025 test and the March 2026 test. This sudden drop in usage suggests the vehicle spent extended periods stationary over the last year, a pattern that requires specific attention regarding tyre flat-spotting and brake disc corrosion. Given the absence of mechanical or structural advisories in the official record, a buyer's physical inspection should focus on the implications of the recent low mileage and stationary periods. Examine the tyre sidewalls for cracking and the tread for uneven wear, as electric vehicles impose immediate torque that stresses stationary rubber. Inspect the brake discs for surface corrosion, a common issue when regenerative braking reduces friction-based cleaning of the rotors, particularly if the car has sat unused. Check the suspension bushes and coil springs for deterioration, as lack of regular use can cause rubber components to perish. Verify the condition of the 12-volt auxiliary battery and the charge port mechanism, ensuring the high-voltage system maintains proper isolation and the regenerative braking system operates without binding calipers or abnormal motor whine.
