2018 BMW 420 2.0L Petrol · WM18 KFX

The vehicle remains roadworthy, but the maintenance history reveals a concerning trend of deferred braking maintenance. While it passed the latest test in June 2025 at 95,997 miles, the tester flagged thin brake pads and worn discs across all four corners. This follows a recurring pattern seen in the June 2024 test at 83,463 miles, where thin pads and pitted front discs were noted. The failure to address these wear-and-tear items despite multiple advisories suggests a reactive rather than preventative maintenance strategy. The mileage accumulation is consistent with an eight-year-old vehicle, averaging approximately 12,000 miles per annum. There is a significant gap of over 12,500 miles between the 2024 and 2025 tests, and another roughly 11,500-mile interval between 2023 and 2024. This steady usage indicates regular operation, which places a predictable demand on mechanical components and consumables, as evidenced by the consistent inner tyre wear issues that led to exposed cords during the 2023 failure. A buyer must prioritise inspecting the front suspension geometry, as the records from 2022 and 2023 repeatedly highlight severe inner edge wear on the front tyres. This typically points to misalignment or worn suspension bushes that have not been corrected. Given the most recent advisories regarding the braking system, a physical inspection of the disc thickness and pad life is essential to ensure the components have not reached a point of mechanical failure, as the tester explicitly advised immediate replacement a year ago.
