2016 MINI Cooper 1.5L Diesel · TH66 AMY

An emerging pattern of tyre degradation and fluid seepage defines the recent mechanical profile of this MINI Cooper, following a period of clean testing between 2021 and 2024. While the vehicle passed its most recent inspection on 16 February 2026, the record shows a recurring advisory regarding the nearside rear tyre, which has been flagged for damage, cracking, or perishing in both 2025 and 2026. This trend, coupled with a front oil leak noted in 2025, suggests that while the vehicle meets minimum legal standards, there are active areas of wear and minor seepage that have persisted or reappeared in recent testing cycles. The vehicle's usage profile is characterised by significantly low mileage for its age, having covered only 35,593 miles over approximately ten years. This equates to an average annual accumulation of roughly 3,559 miles, which is well below the UK national average. Mechanically, such low usage can result in components being subjected to fewer duty cycles but potentially more exposure to environmental degradation due to longer periods of inactivity. This is reflected in the MOT history through the specific advisories for tyre perishing and cracking, which often occur when rubber components are not regularly exercised or are subject to prolonged stationary periods. Prospective buyers should pay close attention to the reported oil leak and the condition of the tyres during a physical inspection and test drive. The front oil leak, though described as not excessive in 2025, warrants a thorough check of the engine bay for any signs of increased weeping or heavy accumulation around seals or gaskets. On a test drive, listen for any unusual engine notes or changes in performance that could indicate the leak is progressing. Additionally, the repeated advisories for the nearside rear tyre suggest that the rubber may be reaching the end of its service life due to age-related perishing rather than just tread wear. Regarding the tyre condition, it is essential to inspect all four tyres for similar signs of sidewall cracking or uneven wear patterns, particularly on the edges. The 2025 advisory specifically noted the nearside rear tyre was worn close to the legal limit on the edge, so check for any steering pull or uneven handling that might suggest alignment issues or suspension component wear. While the 2020 failure regarding the windscreen wiper was a singular event, the overall history indicates that most mechanical components have remained within passing parameters, but the recent shift toward consumables and fluid management issues requires careful verification.
