2018 BMW 420 2.0L Petrol · RF68 MZP

The latest MOT test passed on 28 November 2025, but with advisories noting that the front inner brake discs are pitted or scored and the front brake pads are wearing thin. Reviewing the full history, there is a clear and recurring trend regarding the front braking system, with similar advisories for worn or pitted discs appearing in both 2024 and 2022. This suggests a pattern of reactive maintenance where components are replaced only as they approach the limit of their serviceability, and the current advisories indicate that a full replacement of the front discs and pads is now an impending requirement. The recorded mileage of 53,560 miles over approximately eight years equates to an average annual usage of roughly 6,700 miles. This is relatively low for a vehicle of this age, which typically implies less mechanical stress on the engine and drivetrain. However, low-mileage usage can lead to other issues, such as components degrading due to infrequent use. For example, brake calipers can become prone to binding, and rubber suspension bushes or engine seals can perish or harden when a vehicle is not driven regularly enough to maintain optimal operating temperatures and movement. During your test drive, you should focus heavily on the braking performance and wheel alignment. Listen for any grinding or squealing noises when applying the brakes and feel for any pulsation or shuddering through the pedal, which would indicate significant disc scoring or warping. You should also check for any pulling to one side under braking, which could signal a sticking caliper. Additionally, given the 2024 advisory regarding a tyre worn on the inner edge, inspect the current tread on all tyres for uneven wear patterns, particularly on the inner edges, as this could indicate a need for a wheel alignment or suggest worn suspension geometry. Finally, perform a physical inspection for age-related degradation. Check the tyre sidewalls for any signs of cracking or perishing, which can occur even if the tread depth is sufficient. Examine the engine bay and the underside of the vehicle for any signs of fluid leaks, as gaskets and seals can become brittle over time. It is also essential to verify the service history to ensure that time-based maintenance, such as brake fluid changes and oil services, has been carried out according to the manufacturer's schedule, as fluid degradation is a significant factor in low-mileage vehicles that may have spent periods standing.
