2010 BMW Z4 2.5L Petrol · J100 AAD

The vehicle remains roadworthy but the maintenance history shows a persistent trend of deferred attention regarding metal and rubber components. The most recent test in January 2026 at 43,515 miles passed despite recurring reports of pitting and scoring on both front and rear brake discs. This issue has appeared in every test since June 2023 without any evidence of replacement, indicating that the owner is allowing components to reach a state of surface degradation rather than replacing them as a preventative measure. At 43,515 miles over 16 years, the car has been used infrequently, averaging approximately 2,700 miles per annum. This low usage explains the specific degradation noted in the record. A significant gap in mileage exists between June 2023 and May 2024, where the vehicle covered only 518 miles in a year. Such long periods of inactivity often lead to the perishing of rubber components and oxidation, as evidenced by the perished tyres and cracked sidewalls in the 2023 and 2025 tests. A buyer must conduct a thorough physical inspection of the suspension geometry and braking system. The 2025 test flagged corrosion on both rear suspension arms, following a report of worn bushes on the front lower arms the previous year. While these were not structural failures, the progression from worn bushes to corroded arms suggests the chassis is vulnerable to environmental damage. The brake discs are likely heavily pitted from the car sitting stationary, which can lead to poor braking performance or premature pad wear if not replaced.
