2006 Smart Forfour Passion Semi-Auto 1.5L Petrol · WD55 USS

The most recent DVSA MOT test, conducted on 2025-04-15, resulted in a failure with multiple major defects, including a fractured near-side front coil spring, an inefficient parking brake, and misaligned or incorrectly coloured front lamps, alongside a near-side front wiper that failed to clear the windscreen effectively. This outcome contrasts sharply with the preceding MOTs, which were clean or only recorded minor issues, indicating a significant deterioration in the vehicle’s structural and functional integrity over the past year. The pattern suggests either a failure to address previous advisories and failures promptly or a developing mechanical issue that has escalated beyond the vehicle’s ability to meet roadworthiness standards. The presence of a "Dangerous" parking brake failure in particular is particularly concerning, as it directly impacts the vehicle’s safety and ability to be legally driven. The recorded mileage of 98,267 miles for a vehicle aged approximately 20 years represents a notably low annual usage rate of around 4,913 miles per year, which is unusually low for a car of this age. Such low mileage often correlates with periods of prolonged stationary use, which can exacerbate issues such as corrosion, fluid degradation, and wear from standing rather than from active use. For example, the rear axle end plates showing corrosion and the brake system requiring adjustment or repair may be exacerbated by extended periods without movement, leading to rusting of metal components and potential binding in the braking mechanism. Additionally, while low mileage can reduce wear on consumables like tyres and brakes, the combination of low usage and age means that time-based degradation—such as in the suspension, fluids, and electrical systems—remains a critical factor to monitor. Given the recent MOT failures and the recurring advisories, the prospective buyer should conduct a thorough inspection of the vehicle’s suspension and braking systems. The fractured coil spring is a critical structural failure that compromises ride quality and handling stability; during a test drive, listen for excessive clunking or rattling from the front suspension, particularly when the vehicle is driven over bumps or at speed. The parking brake failure demands immediate attention, as a non-functional system cannot provide the necessary hold-down force under all conditions. Inspect the brake discs for uneven wear, scoring, or corrosion, and listen for grinding or squealing when applying the brakes, which may indicate worn brake pads or a failing caliper. Additionally, check for fluid leaks under the vehicle, particularly around the brake master cylinder and parking brake components, as this could signal a failing hydraulic system. For the tyres, which have shown wear close to legal limits and signs of perishing, examine the sidewall for cracks or delamination, which can compromise tyre integrity and safety. Given the vehicle’s age and the advisories from previous MOTs, consider replacing the tyres if they are worn beyond the legal minimum tread depth or exhibit significant signs of ageing. The rear wheel bearing with excessive play is another critical issue that should be addressed promptly, as a failing bearing can lead to vibration, noise, and eventual bearing failure, which may cause catastrophic wheel detachment. Finally, the buyer should verify that all fluids—including brake fluid, coolant, and transmission fluid—are at the correct levels and free from contamination, as low mileage combined with age increases the risk of fluid degradation over time. A comprehensive service history check, including the last oil change and brake fluid flush, would also be advisable to ensure the vehicle’s long-term reliability.
