2017 BMW M43.0L Petrol

This BMW M4 has demonstrated a consistent roadworthiness trend over the past five years, with every MOT test—including the most recent on 26 March 2026 —resulting in a clean pass at 69,581 miles . There are no recorded defects, advisories, or failures in the available history, suggesting the vehicle has undergone regular servicing and passed all mandatory checks without mechanical or structural issues. However, the 14-month gap between the 2026 and 2025 tests —the longest in the record—means some components may now be approaching their typical service intervals, particularly high-wear items like suspension bushes, brake pads, and fluid systems. The mileage progression reveals a stable usage pattern, averaging 7,731 miles per year since the 2021 test. The jump from 44,327 miles in October 2021 to 45,030 miles by March 2023 —a 700-mile increase in just 17 months —indicates a brief period of lighter use, possibly due to reduced driving frequency. Since then, the mileage has climbed steadily, though the 13,179 miles covered between March 2025 and March 2026 suggests the vehicle has remained in active use. This rate is typical for its age, but the lack of intermediate service records means critical components like timing belts (if applicable), differential fluid, or brake fluid may not have been refreshed at manufacturer-recommended intervals. Given the clean MOT history, a buyer should prioritise an independent inspection of suspension integrity , particularly the rear coil springs and bushes , as these are common failure points in high-performance BMWs at this mileage. The front and rear brake systems —including caliper binding, disc warpage, and pad thickness—should be checked, as the 14-month gap increases the risk of undetected wear. Additionally, the exhaust system warrants scrutiny for corrosion or leaks, especially around flanges and catalytic converters, while the underbody and wheel arches should be examined for structural rust, which can compromise safety-critical components. The fluid levels and condition (brakes, clutch, power steering, and engine oil) should also be verified, as these are not routinely tested in MOTs but directly impact long-term reliability.
