2004 Daihatsu Copen 0.7L Petrol · YD54 AGX

Thishatsu Copen shows a history of persistent structural and mechanical concerns despite its low annual mileage. In the most recent test on January 2025 at 86,140 miles, the vehicle passed after an initial failure for a non-functional offside dipped beam and four perishing tyres. The recurring presence of perishing tyres across multiple years suggests the vehicle sits for long periods, leading to rubber degradation rather than tread wear. More critically, the corrosion on the nearside outer sill has been noted since at least 2023, indicating an ongoing issue that has not been fully addressed. The structural integrity of the vehicle is the primary risk factor. In December 2023 at 81,462 miles, the car failed for excessive corrosion on the offside rear suspension trailing arm mounting area, which significantly reduced structural strength. Additionally, the offside front seat belt anchorage was flagged for significantly reduced strength. While the 2024 test noted the nearside rear seat belt anchorage was only slightly corroded, the history shows a pattern of rust in critical mounting points and sills. The 2020 records also identified corrosion on the front chassis rails, inner sills, and floor, suggesting that moisture-related damage is prevalent on this chassis. Braking maintenance shows a trend of reactive repairs. The front brake discs were noted as pitted and scored in both 2023 and 2024, though they did not reach the point of failure. The vehicle also has a recorded oil leak from 2019 and 2020, which was described as not excessive. A buyer should conduct a thorough underside inspection of the sills and suspension mounting points to ensure the reported corrosion has not progressed to a point of structural failure, as the record indicates the vehicle is vulnerable to significant rust.
