2008 BMW 730 3.0L Diesel · LN57 BBZ

The 2008 BMW 730 currently shows a deteriorating maintenance trend, particularly regarding its chassis and steering components. While the vehicle passed its most recent MOT on November 14, 2025, at 173,477 miles, the list of advisories confirms that the suspension and braking systems are suffering from chronic wear. The recurring nature of these faults suggests that the vehicle is being operated with known mechanical deficiencies that are not being fully rectified between annual inspections. The mileage accumulation is consistent with the age of the vehicle, averaging roughly 9,600 miles per year over its eighteen-year life. The record shows a steady usage pattern, though the frequency of test failures between 2017 and 2025 indicates that the car has required significant intervention to remain roadworthy. The current test is now over eight months old, meaning the vehicle is approaching the next inspection window, and the existing advisories regarding steering rack play and suspension bush wear likely require immediate attention to ensure safety. A prospective buyer must prioritise a thorough inspection of the front suspension geometry, specifically the lower arm bushes and ball joints, which have been flagged repeatedly since 2017. The steering rack inner joints require professional assessment, as play in this area can lead to unpredictable handling and accelerated tyre wear. Furthermore, the brake discs have been noted as pitted and worn for three consecutive years, indicating that the braking system is at the end of its service life and will likely require a full overhaul of discs and pads. The history of structural and safety-related failures, including broken coil springs and tyre structural damage, highlights the importance of inspecting the underside for corrosion and verifying the condition of all four tyres. Given the advanced age and complexity of this 7-series platform, the current advisories should be treated as a baseline for necessary repairs rather than minor cosmetic issues. Any purchase should account for the immediate cost of replacing the worn suspension components and addressing the play in the steering rack to restore the vehicle to a reliable operating standard.
