2004 Toyota Yaris 1.4L Diesel · WV04 UJH

The vehicle is currently roadworthy, but the record reveals a persistent history of structural corrosion requiring proactive management. While the most recent test on 3 July 2026 at 54,780 miles passed, the tester noted that the entire underbody is covered in underseal. This follows a period of significant concern between 2020 and 2023 where the vehicle failed due to excessive corrosion on the rear suspension mountings. The trend suggests that the underlying structural issues have been addressed through repairs and cosmetic protective coatings to halt further degradation. The mileage profile is exceptionally low for a 22-year-old vehicle, averaging approximately 2,490 miles per year. Between the 2021 test at 48,971 miles and the 2026 test at 54,780 miles, the car covered only 5,809 miles. This low usage explains why mechanical components remain despite the age but also correlates with the deterioration of rubber components and the accumulation of rust, which often accelerates when a vehicle sits stationary rather than undergoing wear. A buyer must conduct a thorough inspection of the structural integrity of the rear sills and suspension mounting points. Despite the underseal application, the history shows repeated instances of significant corrosion in these specific areas. Particular attention should be paid to the rear brake pipes and fuel lines, which were flagged as corroded in 2022 and 2024. These lines were covered in grease or material, which can mask the progression of rust until failure. The record also indicates a pattern of neglected consumable maintenance, such as front tyres reaching the legal limit in July 2025 and windscreen wipers failing in 2022. The suspension, specifically anti-roll bar links and axle bushes, has been noted as worn or deteriorated across multiple years. Any physical inspection should check for play in the steering rack and rear axle bushes to ensure the previous repairs have held and that the vehicle remains stable under its low mileage.
