2006 Daihatsu Sirion 1.3L Petrol · WR56 EOS

The vehicle remains currently roadworthy, but the maintenance history indicates a worsening trend regarding structural and suspension integrity. While it passed the latest test in November 2025 at 100,772 miles, the tester flagged multiple advisories for corrosion on all four suspension component mounting areas and both rear coil springs. This represents a progression from the November 2024 test, where only the rear mounts and springs showed issues, suggesting that oxidation is actively spreading across the chassis. At 100,772 miles, the Sirion has averaged approximately 5,000 miles per year, which is significantly below the national average for a vehicle of this age. The mileage accumulation appears consistent, with intervals of roughly 4,000 to 6,000 miles between annual tests. This low usage often suggests lighter mechanical strain on the drivetrain. However, the low mileage does not protect the vehicle from the environmental degradation of rubber components and metal, as evidenced by the worn nearside front suspension arm bush noted in 2024. A buyer must prioritize a thorough underbody inspection of the suspension mounting points to ensure the reported corrosion has not progressed into structural failure. The recurring mention of corroded rear coil springs suggests these components are nearing the end of their functional life. Additionally, the November 2024 advisories for front tyres worn to the legal limit and the 2021 note regarding thin brake pads indicate that basic consumable maintenance has at times been deferred until they reached a critical threshold.
