2017 Smart (mcc) Forfour 1.0L Petrol · GD57 DOG

The most recent MOT test for this 2017 SMART Forfour was conducted on 2025-10-28 and resulted in a clean pass, indicating no defects were found at that time. However, the vehicle’s MOT history reveals a pattern of recurring issues, particularly with front anti-roll bar ball joints and tyre wear, which have caused multiple failures over the past three years. The 2024-11-04 test highlighted both near- and offside front anti-roll bar ball joints as excessively worn, alongside a tyre pressure monitoring system malfunction and dangerous undercutting on the offside front tyre, while the 2022-11-08 advisory noted progressive wear on the offside front inner tyre edge. These repeated failures suggest either a lack of timely maintenance or a fundamental design or installation issue with the suspension components, which could escalate into further structural or alignment problems if not addressed promptly. The recorded mileage of 99,510 miles for a vehicle aged nine years represents an average annual usage of approximately 11,057 miles, which is consistent with typical driving patterns for this model class. There are no evident periods of excessive mileage accumulation or prolonged idling, but the consistent wear on the anti-roll bar ball joints and tyres—particularly the front suspension components—could imply either aggressive cornering, rough road service, or a history of under-maintenance. The tyre advisories from 2022 and 2024 indicate that the offside front tyre was already nearing legal limits by 2022, and the near-side rear tyre was worn close to the limit in 2024, suggesting that tyre rotation or balancing may have been neglected. This wear progression warrants careful inspection, as uneven tyre wear can lead to misalignment, steering pull, or hydroplaning risks. Given the recurring suspension and tyre defects, the prospective buyer should conduct a thorough mechanical inspection before purchase. Focus on the front anti-roll bar ball joints, particularly the near- and offside units, as their excessive wear has been documented in prior MOT failures. Listen for clunking or rattling noises from the front suspension during cornering or over bumps, and check for play or binding in the ball joints when the vehicle is lifted on a jack. The front tyres should be examined for uneven wear patterns, such as feathering or cupping, which may indicate suspension misalignment or camber issues. If the anti-roll bar ball joints are confirmed as worn beyond safe operational limits, replacement is strongly advised to prevent further suspension failure, potential steering instability, or even wheel detachment. In addition to the suspension, the buyer should verify the tyre condition beyond the legal limits—check for sidewall cracking or perishing, which can compromise structural integrity, especially in a vehicle of this age. Inspect the rear tyres for signs of dry rot or excessive edge wear, as these advisories suggest prolonged exposure to edge contact. The vehicle’s battery should be tested for voltage and capacity, as prolonged standing or high mileage can accelerate battery degradation. Fluid levels, particularly the brake fluid, coolant, and differential oil, should be checked for contamination or sludge, as these fluids degrade over time regardless of mileage. If the vehicle has been in storage, ensure that the fuel system is clear of moisture or sediment, and that the exhaust emissions system has not been compromised by rust or blockages. Finally, verify that the service history includes regular oil changes, brake inspections, and suspension servicing, as the absence of these records could indicate a history of neglect.
