2015 BMW M4 3.0L Petrol · WH15 GFE

The vehicle is currently roadworthy, but the maintenance trend shows a recent decline in pre-test preparation. While the car passed its most recent inspection in June 2026 at 73,965 miles, it had failed just one mile prior. This failure involved a damaged offside rear tyre reaching the cords, a non-functional rear fog lamp, and an electronic chassis message in the instrument cluster. The fact that these issues were rectified immediately for the re-test suggests a reactive approach to mechanical upkeep rather than a preventative maintenance schedule. At 73,965 miles, this 11-year-old M4 averages approximately 6,724 miles per year. This low mileage is consistent with a high-performance vehicle that is likely used recreationally rather than for daily commuting. The gap between the August 2024 test at 62,094 miles and the August 2025 test at 68,707 miles shows a consistent usage pattern of roughly 6,600 miles annually. However, the low mileage can sometimes mask the degradation of rubber components and seals due to age. A buyer must conduct a close inspection of the engine and rear differential due to the oil leaks flagged in August 2025. Although the tester noted these were not excessive at the time, oil leaks on high-performance BMW engines often artwork and require expensive gasket or seal replacements. The recurring chassis message mentioned in June 2026 also warrants a diagnostic scan to identify the specific sensor or software fault, ensuring no hidden electrical issues remain. Additionally, the previously missing seat belt buckles noted in 2025 indicate a lapse in basic interior safety standards that the buyer should verify to ensure all safety hardware has been properly replaced.
