2004 BMW Z4 2.2L Petrol · EN04 AAZ

The 2004 BMW Z4 demonstrates stable roadworthiness based on its most recent MOT on 2025-01-06 at 108,580 miles, which passed with no defects. However, the vehicle’s history reveals recurring failures at identical mileages in 2024 and 2022, both recorded without specific defects. These anomalies suggest potential inconsistencies in testing or unresolved minor issues that may have been rectified between tests. The absence of recorded faults in the latest assessment indicates the car is currently compliant, but the pattern of repeated failures at the same mileage raises questions about underlying maintenance practices. The vehicle’s mileage of 108,580 miles over 22 years equates to approximately 4,935 miles annually, significantly below average for its age. This low usage could imply periods of inactivity, increasing risks of rubber component degradation, corrosion, or fluid stagnation. Notably, the MOT records show no gaps longer than 14 months between tests, suggesting consistent compliance. However, the lack of detailed defect reports in prior failures limits insight into specific mechanical concerns, leaving room for unrecorded issues to persist. A buyer should prioritise inspecting the suspension system for worn bushes or coil springs, as low mileage can mask age-related stiffness. Brake components, including calipers and discs, should be checked for binding or uneven wear, given the car’s history of repeated testing. Structural integrity, particularly around the chassis and body panels, warrants scrutiny for hidden corrosion, as inactivity may accelerate rust in vulnerable areas. The absence of recorded defects in the latest test is reassuring, but the vehicle’s maintenance history underscores the need for a thorough pre-purchase inspection to confirm its mechanical soundness.
