2004 BMW Z4 2.5L Petrol · BK04 HVB

The vehicle is currently roadworthy, but the maintenance trend indicates a recent shift toward reactive rather than proactive upkeep. While it passed its latest MOT in April 2025 at 38,123 miles, the failure recorded just days prior reveals a significant lapse in safety-critical inspections. The transition from a clean record in 2023 and 2024 to a multi-point failure in 2025 suggests that components were neglected until they reached critical limits. At 38,123 miles over 22 years, this Z4 has covered an average of only 1,733 miles per year. This low usage profile explains the lack of mechanical wear on the drivetrain but introduces risks associated with age-related degradation. Between March 2024 and April 2025, the vehicle covered only 3,212 miles, yet it suffered multiple failures including worn ball joints and perished tyres. This pattern confirms that the rubber components and metal hardware are reaching the end of their functional lifespan due to oxidation and material failure despite the low odometer reading. A buyer must closely inspect the front suspension assembly, as the April 2025 test flagged both the nearside and offside suspension arm ball joints as excessively worn. These components require immediate replacement to ensure steering precision and safety. The braking system also shows a clear history of neglect, with worn discs noted in 2022 followed by a failure for thin pads and worn discs in 2025. You should verify that the front brakes were fully overhauled following the last test rather than merely topped up. The tyres represent another immediate concern given the low-mile history. The 2025 failure for perishing on the nearside front and a deep cut on the offside rear indicates that the rubber is likely dry-rotted. Check for sidewall cracking across all tyres, as they may be unsafe regardless of remaining tread depth. Given the vehicle's age, a physical inspection for structural corrosion in the sills and under mounting points is essential, as low-mile cars often sit in environments that promote hidden rust.
