2005 Daihatsu Sirion 1.0L Petrol · WX55 NFY

The vehicle presents a concerning roadworthiness profile characterized by a trend of recurring mechanical failures and persistent structural issues. While the most recent test in November 2025 at 100,954 miles resulted in a pass, it followed a failure due to significant emission failures involving carbon monoxide and lambda readings. The tester also noted a binding offside front brake and leaking offside rear shock absorbers, issues that were previously flagged in earlier tests. This suggests a reactive maintenance approach where faults are only addressed to pass inspection rather than resolving underlying mechanical degradation. At 21 years old, the recorded mileage of 100,954 miles is notably low, averaging approximately 4,800 miles per year. However, the data shows a significant increase in usage between 2021 and 2025, where the car covered over 33,000 miles in just four years. This period of activity coincides with the appearance of multiple wear items, including the severe deterioration of the nearside front drive shaft boot which remained a noted defect across several years from 2022 through 2024. A buyer must prioritising the structural integrity of the rear sills and sub-frame. The record shows a progression of corrosion, from minor notes in 2021 to excessive corrosion significantly reducing structural strength in the offside rear mounting by 2023. Given the age of the vehicle, a thorough under-body inspection is mandatory to ensure the rust has not progressed beyond repair. Additionally, the recurring exhaust system failures necessitate a diagnostic check to identify potential leaks or faulty sensors that have repeatedly caused emission failures in 2024 and 2025.
