2017 Smart Forfour 0.9L Petrol · CV67 JVC

The most recent MOT test on 2026-02-24 resulted in a clean pass, marking a positive turnaround after a failure in February 2026, where the vehicle failed due to an exhaust leak affecting emissions compliance. This suggests that any underlying issues with the rear exhaust system have since been addressed, as the subsequent tests since then have shown no further defects. However, the history reveals persistent advisories related to front brake discs showing wear, corrosion in the front shockers, and corrosion of the rear axle, indicating a pattern of recurring wear and potential neglect in addressing these components. The earlier failure in 2024 highlighted tyre wear close to legal limits and structural bulges, which were not rectified, suggesting either inadequate maintenance or a lack of attention to high-wear areas. Overall, while the latest MOT is compliant, the advisories and past failures point to underlying wear that should be monitored closely, particularly if the vehicle is to be relied upon for regular use. The recorded mileage of 15,404 miles for a vehicle aged nine years represents a relatively low annual usage rate of approximately 1,712 miles per year, which is unusually low for its age. This low mileage could imply either infrequent driving, long periods of inactivity, or potential misuse such as prolonged standing in traffic or parking, which accelerates corrosion and fluid degradation. Prolonged idling or stationary use can lead to brake disc corrosion, particularly in the front, where moisture and road salt may accumulate, causing rust and potential binding of calipers. Additionally, suspension components like shockers and axle housings are more susceptible to corrosion when a vehicle remains stationary for extended periods, as condensation can form inside sealed systems, leading to internal failure. The absence of higher mileage figures over the past few years also raises concerns about whether the vehicle has been subjected to typical wear and tear, which could have been mitigated by regular servicing and maintenance. Given the recurring advisories and past MOT failures, the prospective buyer should conduct a thorough mechanical inspection before purchase. Focus on the front brake system, particularly the discs and calipers, as corrosion and binding are evident. Listen for any grinding noises when braking, which could indicate warped or seized discs, and check for uneven brake pad wear or a spongy brake pedal that might signal fluid issues or air in the system. Inspect the suspension for excessive clunking or rattling when driving over bumps, which could reveal worn or corroded shockers or broken suspension bushes. The rear axle should be examined for signs of rust or excessive play, as corrosion in this area could compromise drivetrain integrity. Additionally, verify the tyre condition, especially the front tyres, which have shown structural bulges in the past. Check for uneven tread wear patterns, which may indicate alignment or suspension issues, and ensure there are no cuts or separations in the sidewall that could lead to blowouts. For a vehicle of this age and mileage, particularly one with low annual usage, the buyer should also pay close attention to signs of standing corrosion and fluid degradation. Inspect the battery terminals and cables for corrosion or loose connections, as a 12V battery in a stationary vehicle can degrade over time due to sulfation and reduced charge cycles. Check the brake fluid reservoir for contamination or moisture, as standing fluid can absorb water, leading to reduced braking performance. The exhaust system should be examined for signs of leakage or damage, as the recent MOT failure highlighted potential issues that may have been partially resolved but warrant further inspection. Finally, since the vehicle has not been driven extensively, consider checking for tyre sidewall perishing or cracking, which can occur due to age-related degradation even with low mileage. Ensure that all fluids—oil, coolant, and transmission fluid—are topped up and free from contaminants, and verify that service records are up to date, particularly for time-based maintenance such as brake fluid flushes and oil changes, which are critical for a vehicle that may not be in regular use.
