2004 BMW 645 4.4L Petrol · SP54 AOL

The most recent MOT test, conducted on 3 September 2025 at 101,508 miles, confirms the vehicle passed without any recorded defects, maintaining a clean history over the past two years. There is no evidence of recurring faults or advisories in the last three successful tests, suggesting the vehicle has been consistently compliant with UK roadworthiness standards. However, the single failure in July 2023—though noted as a "no defects" entry—stands out as an anomaly, as it occurred just one day before the subsequent pass. This suggests either a minor oversight in the test or a brief period of non-compliance that was swiftly rectified. Overall, the trend remains stable, with no worsening mechanical issues, but the lack of advisories or defects does not preclude the need for a thorough independent inspection. The recorded mileage of 101,508 miles over 22 years equates to approximately 4,614 miles annually, which is unusually low for a vehicle of this age and type. The gap between the 2022 and 2023 tests—covering 4,168 miles in just over a year—followed by another 900 miles before the July 2023 failure, implies periods of inactivity rather than consistent use. The subsequent 3,636 miles between the July 2023 pass and the August 2023 test suggests the vehicle was either stored or driven sporadically. While low mileage can indicate less wear on high-usage components like brakes and suspension, it also raises questions about fluid degradation (e.g., brake fluid, coolant, transmission fluid) and potential long-term neglect of less obvious systems, such as electrical or emissions-related elements. Given the absence of recorded defects, a buyer should prioritise an inspection of components prone to deterioration over time, particularly those not directly tested during MOTs. The suspension—including coil springs, bushes, and dampers—should be examined for wear, especially if the vehicle has been stored for extended periods, as rubber and metal fatigue can occur even with low mileage. Brake systems, while not flagged in the MOT, warrant scrutiny for uneven pad wear, binding calipers, or corrosion on discs, particularly if the vehicle was driven sporadically. Structural integrity, including underbody corrosion and frame condition, should also be assessed, as rust can develop silently even with limited movement. Finally, the emissions system—though not explicitly tested here—may require attention if the vehicle has been infrequently driven, as catalytic converters can degrade when not operated regularly. A pre-purchase inspection by a qualified mechanic is strongly advised to verify the absence of hidden issues.
