2005 BMW M5 5.0L Petrol · KC55 SXX

The vehicle is currently in a roadworthy state following its most recent pass on 6 May 2025 at 91,564 miles. The maintenance trend appears inconsistent, shifting from a clean pass in early 2023 to a series of failures involving critical mechanical and electrical systems. While the most recent test was successful, the tester flagged perishing and cracking on both rear tyres as an advisory, indicating that rubber components are degrading due to age rather than wear. The car has covered 91,564 miles over 21 years, averaging roughly 4,360 miles per year. This is exceptionally low for an M5, but the MOT data suggests the vehicle has spent significant time stationary. Between February 2024 and May 2025, the odometer moved only 326 miles. Such low usage often leads to the degradation of seals, tyres, and braking components, which is evidenced by the perishing tyres noted in the latest inspection. A buyer must scrutinize the front suspension and braking system. In January 2024 at 91,237 miles, the vehicle failed on excessively worn brake reaction bushes in both front suspension arms and an inadequate handbrake. Although these were rectified for the February pass, the recurrence of suspension wear on a low-mileage car suggests the rubber bushings are failing due to age. The February 2023 failure at 90,605 miles was particularly severe, involving an inoperative engine management light, an SRS airbag fault, and failed exhaust emissions. The history of electrical faults and lambda sensor issues suggests a period of neglect or a lack of regular exercise. You should verify that the SRS system is fully functional and check for any lingering engine management codes. Given the age and the specific failures recorded in 2023 and 2024, a thorough inspection of all rubber suspension mounts and a check for brake caliper seizure is necessary to ensure the car has not suffered from long-term standing.
