2002 BMW M5 4.9L Petrol · T8 NTY

The vehicle is currently roadworthy but the maintenance history reveals a pattern of reactive repairs rather than proactive care. While the most recent test in July 2026 at 102,381 miles passed, it followed a failure just month prior for non-conforming registration plates and a faulty washer system. A persistent issue with a weeping rear diff input seal has appeared in both the June and July 2026 tests, indicating that while the leak is not yet excessive enough to cause a failure, it remains unaddressed. At 102,381 miles, this 24-year-old M5 has travelled sparingly, averaging approximately 4,266 miles per year. The data shows significant gaps in usage, particularly between 2018 and 2020, where the car covered only 888 miles in two years. This period of low mileage often correlates with the degradation seen in rubber components, as evidenced by the 2020 failure for seriously damaged and perished valve stems and the 2026 advisory regarding tyres that are over a decade old. A buyer must pay close attention to the braking and suspension systems. The record shows a long history of corrosion on brake pipes, dating back to 2017, which resurfaced in 2025 as corroded pipes covered in grease. The 2020 inspection noted that brake lines and steering parts were heavily coated in underseal, a technique often used to mask structural rust or corrosion. Additionally, the previous report of play in the offside rear lower suspension arm in 2016 and the loose exhaust bracket in 2022 suggest that the chassis and mounting hardware require a thorough physical inspection to ensure no further structural decay has occurred beneath the underseal.
