2006 BMW 6 Series 4.8L Petrol · M28 POW

The vehicle most recently passed its MOT on 12 November 2025. While the overall maintenance trend appears stable, the presence of multiple advisories indicates that the car is currently approaching a period of required expenditure on routine consumables. The transition from a clean record to one with wear-related advisories suggests that the vehicle has not recently undergone a comprehensive preventative service, meaning the buyer should prepare for immediate maintenance costs to bring the car back to an optimal standard. With a recorded mileage of 99,316 miles over approximately twenty years, the vehicle has averaged fewer than 5,000 miles per annum. This is considerably lower than the national average for a grand tourer of this vintage. While low mileage generally implies less mechanical fatigue on the engine and drivetrain, it often introduces risks associated with prolonged periods of inactivity. Low-usage vehicles are more prone to the degradation of rubber components and the accumulation of moisture in critical fluid systems, which can be more detrimental than the steady wear seen in higher-mileage examples. Immediate attention must be paid to the rear axle consumables. The advisory regarding rear brake pads wearing thin indicates an impending replacement is necessary to avoid scoring the brake discs. Furthermore, the report of rear tyres being worn close to the legal limit and specifically worn on the edges suggests a potential misalignment of the rear tracking or worn suspension bushes. During a test drive, the buyer should listen for any knocks or clunks from the rear suspension and feel for any instability or pulling, which would confirm that the tyre wear is a symptom of a deeper mechanical fault rather than simple tread depletion. Given the vehicle age and low annual usage, a rigorous physical inspection is essential. The buyer should examine all tyre sidewalls for fine cracking or perishing, as tyres often expire due to age before they reach the legal tread limit. Check the brake discs for heavy surface corrosion or binding calipers, which frequently occur when a vehicle stands for extended periods. It is also critical to verify the service history for calendar-based fluid changes; engine oil, brake fluid, and coolant degrade over time regardless of mileage. Finally, the health of the 12V battery should be tested, as low-use luxury vehicles with high electronic loads are particularly susceptible to premature battery failure.
