2018 BMW 420 2.0L Diesel · RF67 SHZ

This 2018 BMW 420 presents a clean and consistent MOT record with no advisories or defects recorded across any of its tests, suggesting it has been kept in good mechanical order throughout its life. The most recent test on 13 February 2026 was a pass with no defects, continuing a stable trend of clean roadworthiness stretching back to 2023. One minor anomaly in the history is a fail recorded on 2 April 2025, which was followed immediately by a pass the very next day on 3 April 2025 with no defects recorded on either occasion. A back-to-back fail-then-pass sequence with no defects listed strongly suggests a minor presentation or administrative issue was resolved on the spot, or that an item was rechecked and found compliant on the retest, rather than indicating any underlying mechanical fault. The overall picture is therefore one of a car that has consistently met MOT standards without any chronic or recurring issues logged by testers. With 104,991 miles accumulated over roughly eight years, this BMW averages around 13,124 miles per year, which sits at the upper end of typical usage for a vehicle of this age and segment. This level of annual mileage is consistent with a car used for regular commuting or substantial motorway travel rather than occasional leisure use. Mechanically, higher-mileage examples of the 4 Series put proportionally greater demand on wear-related consumables, so brake discs and pads, tyres, drive belts, and suspension bushes and coil springs will have experienced significantly more thermal and load cycling than a lower-mileage car of the same vintage. The absence of any advisories related to these components across multiple tests suggests they have either been replaced proactively or remain well within service life, though a buyer should still verify their current state independently. Given the high mileage, particular attention should be paid on a physical inspection and test drive to the suspension system, especially the front control arm bushings, wishbones, and anti-roll bar links, which are known wear items on F-series BMWs and can begin to show play and knocking noises under hard cornering or over uneven surfaces. On the road, listen for any clonking or knocking from the front end over speed humps and listen for creaks from the rear suspension on undulating roads, as well as any vague wandering or looseness in the steering that could indicate worn top mounts or drop links. Brake feel should be tested firmly, checking for any judder through the pedal under heavy stopping which would suggest warped front discs, and ensuring the car pulls up in a straight line without any grabbing or pulling to one side that might indicate a binding caliper or uneven pad wear. Also inspect the underside for any signs of fluid leaks, particularly around the engine oil filter housing, valve cover gasket, and rear differential area, which are common seepage points on higher-mileage BMWs of this generation. For the inspection itself, confirm the tyre tread depths with a proper gauge and check for even wear across each axle, as excessive inner or outer shoulder wear on the front tyres can point toward worn suspension geometry components or incorrect alignment. Inspect the alloy wheels carefully for any kerbing damage and ensure the spare or repair kit is present and in date if applicable. Finally, verify all electronic systems function as expected, including the iDrive infotainment screen, climate control, parking sensors, and any driving mode selectors, as electrical faults on higher-mileage premium vehicles can become costly to remedy. A pre-purchase inspection by a BMW specialist or independent garage remains strongly advisable to provide peace of mind before committing to a purchase of this high-mileage but otherwise well-documented example.
