2021 MINI Cooper S Electric Level 3 Electric · DN71 PRX

The latest MOT test for the 2021 MINI COOPER S ELECTRIC occurred on 2025-12-04, resulting in a clean pass with only a single minor defect related to a damaged windscreen that did not impair the driver’s field of vision. This follows a pattern of two prior MOTs—one in December 2024 and another in December 2025—where the only recorded defects were minor and non-critical, indicating a generally stable maintenance record. The failure in December 2023, which included a dangerous tyre defect and a severely distorted front offside road wheel, stands out as an outlier, suggesting either a pre-existing structural or manufacturing issue or an incident that caused significant damage. While the subsequent MOTs have been passed, the presence of a major defect in 2023 raises concerns about the integrity of the front offside wheel assembly, which may warrant further investigation into whether this was a one-off incident or a recurring problem with the wheel’s structural or mounting integrity. The recorded mileage of 34,162 miles for a vehicle aged five years represents a moderate annual usage rate of approximately 6,832 miles per year, which is within the expected range for a car of this age and type. The consistency of this mileage suggests a steady, albeit not particularly high, level of usage, which typically indicates that wear on consumables like brakes, tyres, and fluids has been gradual rather than accelerated. However, the absence of recent high-mileage spikes or long periods of inactivity does not preclude potential issues from prolonged standing, such as corrosion to the brake system, particularly if the vehicle was left unused for extended periods. Additionally, the 2023 MOT failure highlights that even moderate mileage can expose latent defects, especially in components like wheels and tyres, which may have been compromised before becoming apparent during the test. Given the recent MOT history, the buyer should prioritise a thorough inspection of the front offside wheel assembly and associated suspension components, as the 2023 failure suggests a potential weakness in this area. On a test drive, listen for unusual noises from the front suspension, particularly clunks or rattles that may indicate loose or worn suspension bushes, coil spring degradation, or binding calipers. Inspect the front offside wheel for any signs of uneven wear, cracks, or bulges, and verify that the wheel is securely mounted and aligned. The tyre with the bulge from 2023 should be replaced immediately, as a failed tyre is a critical safety hazard and cannot be repaired. Additionally, check the vehicle’s brake system for signs of corrosion or binding, especially around the offside front brake discs and calipers, as prolonged standing can accelerate wear and corrosion. For the rest of the vehicle, the buyer should focus on age-appropriate checks given the moderate mileage and recent MOT history. Examine the tyres for sidewall perishing or cracking, which can occur even with moderate usage over time, particularly in the MINI’s exposed rubber components. Verify the condition of the 12V battery, as electric vehicles can experience battery degradation more rapidly with age, and check for any fluid leaks around the battery, exhaust system, or undercarriage that could indicate oil or coolant seepage. Inspect the exhaust emissions system for corrosion or structural damage, as the electric drivetrain may be more susceptible to rust in exposed areas. Finally, since the vehicle has not undergone a full service in the last 12 months, consider checking the service book for any scheduled fluid top-ups, particularly brake fluid (which should be replaced every two years or 60,000 miles, whichever comes first) and coolant, as these fluids degrade over time regardless of mileage. A professional inspection of the electric drivetrain components, such as the inverter and motor, is also advisable, though this may require specialist equipment.
