2017 BMW 420 2.0L Diesel · AF67 RYZ

The vehicle most recently passed its MOT on 27 November 2025, though this followed a failure three days prior. The failure was categorized as dangerous due to exposed ply and cords on both rear tyres, indicating a significant neglect of basic safety inspections. While the broader history shows a consistent pattern of clean passes from 2021 through 2024, the recent failure suggests a lapse in proactive maintenance regarding consumable wear and safety. With a recorded mileage of 43,320 miles over approximately nine years, the vehicle has averaged roughly 4,813 miles per year. This is considerably lower than the national average for a BMW 4 Series. While low mileage generally implies less mechanical wear on the drivetrain and suspension, it often introduces risks associated with prolonged periods of standing, such as the degradation of rubber components and the accumulation of moisture or corrosion within the braking system. Particular attention must be paid to the rear tyres and wheel alignment. The MOT history reveals a recurring issue with the inner edges of the rear tyres, dating back to 2020, culminating in the dangerous failure in 2025. This pattern strongly suggests a misalignment of the rear tracking or worn suspension bushes. During a test drive, listen for abnormal road noise or a tendency for the vehicle to drift. Inspect the current tyres for uneven wear patterns across the tread width, as this will indicate whether the underlying alignment issue has been professionally rectified. Given the low annual usage, a physical inspection should focus on age-related deterioration rather than mileage-based wear. Check the tyre sidewalls for fine cracking or perishing, as rubber degrades over time regardless of tread depth. Examine the brake discs for surface corrosion or evidence of binding calipers, which can occur when a car is left stationary for extended periods. Finally, verify the service history to ensure that engine oil and other critical fluids have been changed according to the manufacturer's calendar intervals rather than mileage, and test the 12V battery health to ensure it has not been depleted by infrequent use.
