2009 Daihatsu Sirion 1.0L Petrol · SC09 UDH

The vehicle is currently roadworthy but the maintenance history reveals a concerning trend of escalating corrosion and component wear. While the most recent test in June 2025 at 77,684 miles secured a pass, it followed a significant failure just one month prior that flagged multiple mechanical and structural defects. The transition from the May 2025 failure to the June 2025 pass suggests that while repairs were made to address immediate failures, the underlying condition of the vehicle remains subject to a reactive maintenance pattern rather than proactive preventative care. At 17 years old, the recorded mileage of 77,684 miles represents a low average of approximately 4,570 miles per year. This low usage profile correlates with the presence of age-related degradation seen in the records. Between April 2023 at 74,798 miles and the May 2025 test at 77,673 miles, the car covered only under 3,000 miles. Such low mileage often leads to the perishing of rubber components and accelerated corrosion of metal surfaces, as the vehicle spends long periods sitting stationary rather than being driven. A buyer must conduct a thorough physical inspection focusing on the recurring corrosion issues on the chassis. The tester has repeatedly identified corrosion on the front subframe mountings and coil spring mountings across multiple years. While these were not marked as excessive yet, the persistence of these faults indicates the structural integrity is degrading. The May 2025 failure also highlighted an excessive oil leak from the engine and corroded fuel pipes, which require immediate verification to ensure they do not pose a fire risk or further mechanical failure. The suspension and braking systems also require close scrutiny. The May 2025 record noted excessively worn anti-roll bar ball joints and suspension arm bushes, alongside perished tyres. Furthermore, the history of corroded offside and nears brake pipes and pitted front discs suggests the braking system is reaching the end of its functional life. The buyer should check for signs of fluid leaks and verify the condition of all rubber bushings and boots, as the low-mileage, high-age profile makes these components particularly vulnerable to rapid environmental decay.
