The vehicle currently holds a valid roadworthiness status following a successful MOT test on 23 April 2025 at 85,715 miles. While the most recent inspection recorded no defects, the maintenance history reveals a recurring pattern of immediate failures followed by re-tests. In both 2024 and 2025, the car failed the initial test but passed upon follow-up inspection just days later. This suggests a reactive maintenance approach where faults are only addressed once they trigger a failure rather than through proactive preventative servicing. The trend remains stable in terms of passing but indicates a lack of a rigorous independent inspection schedule. The vehicle has accumulated 85,715 miles over approximately five years, averaging roughly 17,143 miles per year. This figure exceeds the national average for a luxury executive car and indicates heavy motorway use or high-frequency operation. Between the May 2024 test and the April 2025 test, the car covered 13,263 miles in just under eleven months. Such a rapid accumulation of mileage places significant strain on high-wear components typical of the 7-series platform, particularly the complex mild-hybrid system, the air suspension components, and the braking assembly. Because the MOT records do not specify the mechanical reasons for the initial failures, a buyer must conduct a thorough physical inspection of high-stress areas. The high mileage necessitates a close look at the suspension bushes, control arm ball, and leaking dampers, which often degrade at this interval. The buyer should also inspect the brake discs for thinning and calipers for binding, as the high usage profile correlates with accelerated consumable wear. Given the history of failures, verifying the integrity of the exhaust system and checking for any minor underbody corrosion is essential to ensure the previous faults were rectified properly rather than merely masked.
