2017 Smart (mcc) Forfour 0.9L Petrol · AF67 WMU

The most recent MOT test on 2026-02-03 resulted in a passing outcome, though it revealed persistent brake-related advisories that have been recurrent over the past five years. The pattern of thin brake pads and worn, yet not dangerously compromised, front brake discs suggests a consistent but unresolved issue with brake system longevity. While the 2025 test showed no defects, the 2021 and 2020 advisories on tyre wear and front brake conditions indicate that the vehicle has not been fully serviced to address these wear patterns, particularly on the front brakes. This trend, combined with the failure in 2025 due to rear tyre tread depth, highlights a need for proactive maintenance rather than reactive patching, as the wear progression appears systematic rather than sporadic. The recorded mileage of 58,396 miles for a vehicle aged nine years represents an average annual usage of approximately 6,488 miles, which is within the expected range for a compact city car of this class. However, the absence of service records or a clear pattern of high-mileage accumulation suggests either light use with extended periods of stationary storage or a lack of regular servicing. Standing vehicles, especially in a small car like the SMART, are particularly vulnerable to issues such as brake pad glazing from heat buildup, corrosion in the brake caliper pistons or brake fluid contamination from moisture ingress, and tyre sidewall perishing due to prolonged exposure to UV light and oxygen. The tyre advisories from 2020 and 2021, particularly the edge wear, may also indicate misalignment or suspension wear contributing to uneven tyre contact, which could exacerbate future brake and suspension failures. For a prospective buyer, the most critical areas to inspect are the front brake system, given the recurring advisories. Visually check the brake pads for even thickness and signs of glazing or scoring, and listen for a metallic grinding sound when braking, which could indicate pad-to-disc contact or warping. Inspect the front brake discs for warping, scoring, or uneven wear, and ensure there is no binding in the calipers when the vehicle is stationary—this may suggest seized caliper pistons or seized brake hoses. Test the braking performance on a drive, paying close attention to pedal feel; a spongy or soft pedal could signal air in the brake fluid or a failing master cylinder, while a firm but consistent stop is preferable. Additionally, check the rear tyres for consistent tread wear patterns and signs of dry rot or cracking in the sidewall, as the 2025 failure highlights the importance of maintaining adequate tread depth. Since the vehicle has not undergone a full brake service in recent years, consider budgeting for a professional inspection of the brake fluid condition and a potential brake pad and disc replacement if the wear is severe. Beyond the brakes, the suspension and tyre condition warrant immediate attention. The tyre wear advisories suggest potential misalignment or suspension component wear, so inspect the suspension for excessive play in the steering or clunking noises when driving over bumps, which could indicate worn suspension bushes or damaged coil springs. Check for uneven tyre wear, as this often points to alignment or suspension issues, and ensure the tyres are within legal limits, with no visible signs of dry rot or sidewall damage. Given the vehicle’s age and usage profile, a thorough check of the engine oil level and condition is prudent, as oil degradation over time can lead to increased wear on the engine components. Finally, verify the condition of the 12V battery and associated electrical systems, as prolonged standing can lead to corrosion in the battery terminals or alternator output issues, which may not be apparent during a test drive but could cause problems in the long term. If the vehicle has been stationary for extended periods, consider a professional inspection of the battery and starter motor to ensure they are in good working order.
