2013 BMW 135 3.0L Petrol · NL63 MZU

The vehicle is currently roadworthy, though the maintenance trend shows a shift from reactive repairs to neglect. The most recent test in September 2025 at 48,852 miles passed without major failures, yet the tester noted that engine covers and undertrays were obstructing a full view of critical components. This suggests that while the car meets minimum legal standards, the physical state of the underside may be masking ongoing issues or corrosion identified in the previous year. The mileage data is highly inconsistent with the vehicle's thirteen-year age. While the current record of 48,852 miles suggests a low average of approximately 3,700 miles per year, the September 2024 test recorded 66,395 miles indicates a significant burst of over 17,000 miles in a single year. This discrepancy suggests the car may have sat stationary for long periods between intervals of use, which often leads to degradation of rubber-based components rather than mechanical wear from distance. A physical inspection must focus on the implications of low annual mileage and the recorded faults. The 2024 test flagged all four tyres for cracking and perishing, a classic symptom of age-related dry rot rather than tread wear; any buyer should verify the date codes on the current tyres to ensure they are not aged. The non-excessive oil leak noted in 2024 requires a close look at the valve cover gaskets and seals, as the presence of engine covers mentioned in the latest test could hide whether this leak is worsening.
