2018 BMW M3 3.0L Petrol · X4 OSX

The February 2026 test at 40,611 miles returned a clean pass with no defects or advisories recorded, continuing a pattern of trouble-free MOT outcomes stretching back to December 2022. The maintenance trend is stable; the only blip appears in January 2025 when the car failed at 33,141 miles then passed a retest four miles later at 33,145 miles, suggesting a minor rectification such as a bulb or wiper blade rather than a systemic fault. Annual mileage has hovered around 3,400 miles between the 2022, 2024 and 2025 tests, but the most recent interval shows a jump to roughly 7,500 miles in thirteen months. That increase aligns with the car entering its eighth year and may reflect a change of keeper or simply more regular use. No extended gaps appear in the test record; each examination falls within a month of the anniversary, indicating the vehicle has remained taxed and on the road without long periods of storage. With no advisories logged across five consecutive tests, the suspension bushes, coil springs, brake discs and structural panels have not drawn tester attention for corrosion or wear. That absence is noteworthy on an eight-year-old M3, though it does not guarantee components are pristine — testers only flag items that meet the failure threshold. A pre-purchase inspection should still concentrate on the rear multi-link suspension for bush degradation, the front control-arm ball joints, and the brake calipers for any sign of binding after the recent mileage uptick. The underside deserves close scrutiny for early structural corrosion around the rear subframe mounts and inner sills, areas the MOT may not expose until perforation occurs.
