2018 BMW 420 2.0L Petrol · WR68 AEA

The vehicle’s most recent MOT test, conducted on 27 July 2024 at 60,019 miles, confirms it remains roadworthy with no defects recorded. However, the immediate preceding test on 25 July 2024—just two days earlier at 60,018 miles—was a failure without any defects logged. This anomaly suggests either a procedural oversight in the MOT process or a temporary administrative issue rather than a mechanical trend. The previous clean passes in November 2023 (57,398 and 57,395 miles) and October 2022 (46,055 miles) indicate no recurring mechanical failures, though the double-testing in 2023 and 2024 warrants scrutiny of whether the vehicle was driven between tests or if the failure was spurious. The recorded mileage progression shows consistent annual usage, averaging around 7,500 miles per year—a typical rate for a vehicle of this age. There are no prolonged periods of inactivity or rapid mileage spikes that might suggest neglect or heavy usage. The gap between the 2022 and 2023 tests (11,343 miles in 11 months) and the 2023 to 2024 interval (2,621 miles in 6 months) aligns with steady driving patterns. However, the double-testing in consecutive years raises questions about whether the vehicle was moved between tests or if the failure was a one-off administrative error. Given the lack of defects in the MOT history, a buyer should prioritise an independent inspection of high-wear components that are not routinely checked in standard MOT tests. Focus on the suspension system—particularly the condition of coil springs, bushes, and dampers—for signs of degradation or leaks, as these are critical for handling and safety. The braking system should be thoroughly assessed, including rear caliper binding (a common issue in BMWs) and the integrity of brake discs and pads, even though no failures were recorded. Structural corrosion, particularly around wheel arches, sills, and the subframe, should be examined, as this is often overlooked in MOTs but can compromise long-term reliability. Finally, verify the integrity of the exhaust system and catalytic converter, as emissions-related failures are not always apparent until they become severe. The absence of advisories in the MOT history is reassuring, but these components demand close scrutiny given the vehicle’s age and mileage.
