2005 Smart Forfour 1.5L Diesel · KX55 YLB

The vehicle is currently roadworthy, but the maintenance trend shows a shift toward deteriorating rubber and steering components. The most recent test in October 2025 at 80,537 miles passed despite the tester identifying severe deterioration of both front drive shaft CV boots and play in the front track rod end ball joints. This represents a regression from the clean record in October 2024, suggesting that while the car is operational, mechanical components are now being addressed as they reach a point of failure rather than through preventative maintenance. At 21 years old, the recorded mileage of 80,537 miles averages approximately 3,835 miles per year, which is significantly low for a vehicle of this age. The data shows consistent but infrequent usage, with only 3,002 miles driven between the October 2024 and 2025 tests, and another 3,002 miles in the following year. This low-frequency driving pattern often leads to accelerated degradation of rubber components and corrosion from standing stationary, which aligns with the recurring issues found in the service history. A buyer must conduct a thorough physical inspection of the front suspension and braking system. The history highlights a persistent issue with the offside front brake pipe, which failed in 2023 due to corrosion and failed again in 2024 for excessive corrosion; ensure this pipe was fully replaced and not merely cleaned. Furthermore, the recent deterioration of the CV boots and play in the track rod ends require immediate attention to prevent damage to the drive shafts and steering geometry. Check for any further structural corrosion on the undercarriage, as the low-mileage status often masks hidden rust in vehicles that are not driven regularly.
