2016 BMW 420 2.0L Petrol · AX16 ATV

The most recent MOT inspection on 19 November 2025 resulted in a pass, but the vehicle's maintenance trend shows a concerning pattern of recurring tyre-related issues and neglected consumables. While the vehicle has passed its recent tests, the history reveals a cycle of dangerous failures and multiple advisories regarding tyre tread depth and structural integrity. The 2023 failure due to critically thin rear brake pads, combined with the repeated advisories for worn tyres across multiple years, suggests a reactive rather than proactive approach to maintenance. This pattern indicates that components are often only addressed when they reach the point of legal failure or safety risk, which can lead to secondary wear on other components like suspension bushes or brake discs. With a recorded mileage of 58,770 miles over approximately ten years, this BMW 420 has averaged roughly 5,877 miles per year. This is significantly lower than the UK national average, suggesting the vehicle has been used for light commuting or short trips. While lower mileage generally implies less mechanical wear on the engine and drivetrain, such low annual usage can be detrimental if the vehicle has spent long periods stationary. Infrequent use often leads to accelerated degradation of rubber components, fluid contamination, and corrosion of braking surfaces. You must verify if the service history includes calendar-based intervals rather than just mileage-based ones, as oil and brake fluid require replacement based on time to prevent internal sludge and moisture buildup. The recurring advisories for tyres being worn on the edges or near the legal limit are a significant red flag. This specific type of wear often points to underlying suspension or alignment issues, such as worn control arm bushes, damaged coil springs, or incorrect camber settings. During your test drive, listen closely for any rhythmic thumping, humming, or vibration from the tyres, and pay particular attention to how the car tracks straight on a level road. If the steering feels vague or if there is a pulling sensation to one side, the wheel alignment or suspension geometry likely requires immediate attention. Furthermore, the previous history of tyre bulges and sidewall cracking suggests that even if the tread depth is currently sufficient, the rubber may be perishing due to age and UV exposure. Given the vehicle's profile of low mileage and potential periods of standing, you should conduct a thorough physical inspection of all rubber components. Check the sidewalls of all tyres for fine cracks or perishing, and inspect the drive belts and coolant hoses for signs of hardening or brittleness. Examine the brake discs for heavy surface corrosion or pitting, which can occur if the car is not driven regularly enough to clear the oxidation. Additionally, check the battery health, as low-usage vehicles are prone to discharge and capacity loss. Finally, confirm that the service book shows regular oil changes to ensure that the engine has been protected against the moisture accumulation typical of short-trip driving patterns.
