2015 BMW Z4 2.0L Petrol · SW15 CZC

The vehicle is currently roadworthy, but the maintenance trend indicates a shift toward reactive rather than proactive care. While the most recent test on 28 July 2025 at 60,986 miles passed, it followed a failure just two days prior due to a critical structural failure in the nearside rear inner tyre and excessive edge wear on the offside rear tyre. This suggests the previous owner only addressed safety defects when forced by an MOT failure rather than monitoring tyre condition independently. At 11 years old, the recorded mileage of 60,986 miles represents a low average of approximately 5,544 miles per year. The data shows consistent usage between tests, with roughly 9,000 miles covered between August 2023 and August 2024, and another 11,393 miles between August 2024 and July 2025. This low annual mileage often leads to degradation of rubber-based components, such as bushings and seals, which can become brittle with age despite the low odometer readings. A buyer must scrutinise the persistent front oil leak, which has been flagged in both the 2024 and 2025 tests. Although the tester noted the leak was not excessive, its recurring nature suggests a failing valve cover gasket or oil filter housing seal that will eventually require more costly intervention. Given the recent failure for inner tyre wear, a physical inspection of the rear suspension geometry and control arms is essential to ensure no misalignment or worn components are causing the premature tyre degradation.
