2005 Smart Forfour Coolstyle 1.1L Petrol · YC55 YHE

The vehicle remains currently roadworthy but the maintenance history shows a worsening trend regarding structural and braking system integrity. While the most recent test in October 2025 at 80,858 miles passed, the tester identified several new defects that were not present in previous years. The recurring appearance of corroded brake pipes across multiple corners and a newly noted exhaust leak indicate that the vehicle's underbody components are succumbing to age-related degradation despite the low annual mileage covered. The mileage profile is exceptionally low for a 21-year-old vehicle, averaging approximately 3,850 miles per year. The data shows consistent short-term usage, with only 849 miles driven between the October 2024 and October 2025 tests. This rate of use often preserves internal engine components but suggests the car may have sat for long periods. Such inactivity frequently leads to the accelerated corrosion of metal surfaces and the degradation of rubber-based components, which aligns with the persistent rust and suspension mounting issues flagged in the MOT records. A buyer must conduct a thorough physical inspection of the rear inner sills and suspension mounting points. The record notes repairs to these areas being covered in underseal in both 2024 and 2025, which often indicates an attempt to mask structural corrosion. It is vital to peel back the underseal to ensure the metal underneath is structurally sound rather than merely patched. Furthermore, the brake pipes have been flagged for corrosion consistently since 2022; these should be replaced proactively to prevent a sudden failure, as the corrosion appears to be spreading toward the front of the vehicle.
