2006 BMW M5 5.0L Petrol · GD06 BDY

The vehicle remains technically roadworthy, though the maintenance history indicates a recurring trend of progressive braking component degradation. The most recent test in September 2025 at 178,365 miles flagged an advisory for front brake discs being worn, pitted or scored. This follows a pattern seen in 2023 where the offside front disc showed internal corrosion, and 2021 when rear discs exhibited pitting. While the car passed its latest inspection without failures, the persistent mention of brake hardware suggests that the system is reaching the end of its service life across multiple axles. At 178,365 miles, the vehicle has averaged approximately 9,000 miles per year over its twenty-year lifespan, which aligns with typical annual usage patterns. The mileage data shows consistent movement, with roughly 4,000 to 4,500 miles covered between annual MOT tests from 2021 through 2025. This regularity suggests the car has not sat stationary for long periods, though the high cumulative mileage places significant stress on the high-performance drivetrain and suspension components inherent to the M5 model. A buyer must prioritise a thorough inspection of the braking system and fluid lines. The 2022 test identified corroded nearside and offside front brake pipes covered in grease, which often masks deeper structural decay of the metal lines. The previously non-excessive engine oil leak noted in 2022 should be re-evaluated to ensure it has not worsened into a more significant leak. Given the recurring advisories regarding worn discs, a physical check for sticking calipers and worn suspension bushings is essential, as these often fail alongside disc components at this mileage interval.
