2004 Smart City Coupe 0.7L Petrol · YK04 TPS

The vehicle presents a concerning roadworthiness profile with a maintenance history defined by reactive repairs rather than preventative care. While it passed its most recent test in June 2025 at 78,850 miles, the record reveals a pattern of recurring mechanical failures and persistent emission issues. The trend is unstable, as critical defects such as brake pipe corrosion and suspension wear have appeared repeatedly across multiple years and tests, suggesting that faults are only addressed when necessary to secure an MOT certificate. At 78,850 miles, the car shows exceptionally low mileage for a 22-year-old Smart Coupe, averaging approximately 3,600 miles per year. The data indicates a period of low activity between February 2024 and March 2025, where the vehicle covered only 2,066 miles in over fourteen months. This low-use pattern often correlates with the degradation of rubber components and internal corrosion, which is evidenced by the consistent reports of deteriorated brake pipes and perished suspension bushes despite the low overall mechanical wear. A prospective buyer must conduct a thorough physical inspection of the braking system and suspension geometry. The tester repeatedly flagged excessive corrosion on all four brake pipes between 2023 and 2025, indicating a high risk of fluid leaks or line failure. The front suspension shows a history of worn drop links and deteriorated dust covers, which can compromise handling and safety. Furthermore, the nearside front wheel bearing noted as noisy in 2025 requires checking for play to ensure it has not progressed toward seizure. The engine management system warrants scrutiny due to repeated emission failures. In 2023 and 2025, the vehicle failed based on high carbon monoxide, hydrocarbon, and lambda readings, alongside an inoperative engine management light and inability to complete emissions tests. The presence of an ongoing oil leak noted in 2023 should also be monitored to ensure it is not affecting auxiliary components or belts. Given the age of the vehicle, the structural integrity of the chassis and mounting points must be verified for hidden rust that was not fully detailed in the advisories provided.
