2004 Smart City Cabriolet 0.7L Petrol · BX04 VMK

The vehicle remains currently roadworthy, though the maintenance trend shows a developing issue regarding the braking system components. The most recent test on 09 June 2026 at 50,562 miles identified a corroded offside rear brake pipe covered in grease or other material. This mirrors an identical advisory from the 17 June 2025 test at 49,177 miles. While the vehicle passed despite this finding, the recurrence of this specific fault suggests that the corrosion is progressing or has been masked rather than repaired, indicating a risk of future failure. The mileage profile is exceptionally low for a 22-year-old vehicle, averaging approximately 2,298 miles per year. Between June 2022 and June 2026, the car covered just 4,941 miles, representing a consistent low usage pattern of roughly 1,235 miles annually. This low mileage often implies less mechanical wear on the drivetrain and engine components, but it also increases the likelihood of degradation in rubber components, seized seals, and accelerated corrosion due to the vehicle sitting stationary for extended periods. A buyer must focus their physical inspection on the offside rear brake assembly to determine the extent of the pipe degradation. The presence of grease or material on a corroded pipe often indicates an attempt to hide weeping leaks or structural thinning of the metalwork. Given the age of the Smart and the low mileage, the inspection should also prioritize the structural integrity of the chassis for rust, which is common in older cabriolets of this era. Checking for perished suspension bushes and seized brake calipers is essential, as these parts often fail through age regardless of the low mileage driven.
