2005 BMW 645 4.4L Petrol · LX55 VPN

The 2005 BMW 645 presents a generally stable mechanical condition, culminating in a clean pass on 13 November 2025 at 148,305 miles with zero defects. The maintenance trend over the past five years shows a resolving pattern regarding corrosion and braking efficiency, though historical issues required careful monitoring. The tester flagged corroded rear brake pipes in November 2023 at 146,832 miles, yet the vehicle passed without such corrosion advisories in 2024 and 2025, suggesting remedial work was carried out. Similarly, the parking brake efficiency advisory from November 2021 at 138,709 miles reappeared in November 2024 at 147,451 miles, indicating a recurring marginal condition that barely meets the legal threshold rather than a sudden failure. Accumulating 148,305 miles over 21 years results in an average annual mileage of roughly 7,062 miles, which is entirely typical for a vehicle of this age. The record shows consistent usage without significant gaps or rapid accumulation. Between the November 2021 test at 138,709 miles and the November 2022 test at 143,590 miles, the car covered 4,881 miles, and it continued this steady pace, adding 854 miles by November 2023, 619 miles by November 2024, and 854 miles by November 2025. This low-mileage profile implies lighter use, but prolonged periods of standing can accelerate rubber degradation and localised corrosion, meaning a physical inspection of seals and bushes remains essential. A prospective buyer must thoroughly inspect the undercarriage and braking components before purchase. The 2023 advisory regarding corroded rear brake pipes covered in grease raises concerns about the overall condition of the steel hydraulic lines and the structural integrity of the underbody. Although undertrays were fitted during the 2024 test, these often trap moisture against the chassis, potentially hiding advanced corrosion on suspension mounting points and subframes. The recurring marginal parking brake efficiency points toward a binding caliper or stretched cables, requiring a road test to verify the handbrake holds securely on an incline. Suspension components also warrant close scrutiny; the slight play detected in the offside front track rod end ball joint in 2021 may have progressed, and the worn tyres flagged in the same year suggest potential misalignment or worn suspension bushes that could cause uneven tyre wear on the current set.
