2004 BMW Z4 3.0L Petrol · LG04 CWR

The vehicle is currently roadworthy, but the maintenance trend shows a concerning decline in the suspension and steering components. While it passed the March 2026 test at 116,371 miles, it failed just days prior due to multiple defects in the steering rack inner joints and lower suspension arm ball joints. These issues indicate that the front-end geometry is reaching the end of its functional life and requires immediate mechanical attention. At 116,371 miles over 22 years, the Z4 has covered a relatively low average of approximately 5,290 miles per year. This low usage suggests infrequent roadion, but the gaps between tests—such as the 876-mile interval between January 2024 and February 2025—may contribute to the degradation of rubber components and seals, which is evidenced by the severely deteriorated anti-roll bar ball joint dust cover noted in 2023. A prospective buyer must conduct a thorough inspection of the front suspension assembly, as the history shows recurring play in the steering artwork and ball joints across the last three years. There is also documented evidence of fluid leaks, with a coolant leak noted in 2024 and a non-excessive oil leak in 2025. Furthermore, the rear brake pipes should be inspected for corrosion, as they were flagged in 2025 for being covered in grease, which can mask structural decay if not addressed.
