2018 BMW 640 3.0L Diesel · CN18 ADE

The vehicle demonstrates a stable roadworthiness record, with all five MOT tests passing without defects. The most recent 2025-11-07 inspection at 43,074 miles confirmed no issues, aligning with prior results from 2024-11-04 (32,533 miles), 2023-11-10 (24,321 miles), 2022-12-07 (20,042 miles), and 2021-12-21 (10,696 miles). No recurring faults or escalating concerns were flagged across this eight-year span, indicating consistent maintenance and minimal mechanical degradation. The mileage progression reflects a steady annual accumulation of approximately 5,384 miles, which is below the typical average for a vehicle of this age. Notably, the 2021-12-21 test at 10,696 miles suggests the car was driven sparingly in its early years, with a sharp increase to 20,042 miles by 2022-12-07. Subsequent tests show gradual growth, reaching 43,074 miles by 2025. This pattern implies either infrequent use or potential periods of inactivity, which could affect components like the battery, fluids, and drive train if not regularly exercised. The MOT history remains entirely clean, with no advisories or failures. A buyer should prioritise inspecting suspension components, particularly bushes and coil springs, which may degrade during prolonged inactivity. Brake discs and calipers should be checked for corrosion or uneven wear, as low mileage can sometimes mask underlying issues. The exhaust system and structural integrity warrant scrutiny, as rust or fatigue might develop in less-used vehicles. While the MOT records confirm no immediate risks, the low mileage and age necessitate a thorough pre-purchase inspection to verify component condition beyond standard testing.
