2004 BMW Z4 3.0L Petrol · LS54 OBT

The vehicle is currently roadworthy, though the maintenance history indicates a reactive rather than proactive approach to repairs. The most recent test on 26 May 2026 at 91,567 miles saw a failure due to an ineffective fuel cap and slightly contaminated brake fluid. While these issues were rectified to secure a pass, the presence of fluid contamination suggests that fluid intervals may have been neglected. The overall trend remains stable in terms of passing, but the recurring minor failures point to basic maintenance oversight. At 22 years old, the recorded mileage of 91,567 miles represents a low annual average of approximately 4,162 miles per year. The data shows consistent usage over the last three years, with only 2,228 miles driven between May 2025 and May 2026, and 740 miles between May 2024 and May 2025. This low mileage often reduces mechanical wear on the drivetrain but increases the risk of rubber component degradation and fluid breakdown when the vehicle sits for extended periods. A buyer must conduct a close inspection of the exhaust system and suspension components. The 2024 test flagged wear on the nearside steering arm and rust on the front exhaust fixing bolts, while the 2023 record noted rusty rear discs and a deteriorating exhaust. These areas should be checked for structural corrosion to ensure the rust has not progressed beyond surface level. Given the recent failure for contaminated brake fluid, a full system flush is necessary to ensure the hydraulic system is operating within factory parameters.
