2007 Daihatsu Terios 1.5L Petrol · SU56 AAN

The vehicle presents a concerning structural profile with a worsening trend in corrosion that remains a persistent issue. While the November 2025 test at 106,484 miles resulted in a pass, the record shows a cumulative buildup of advisories regarding the front subframe, rear axle, and all four suspension arms. This follows a significant failure in December 2023 at 100,317 miles, where excessive corrosion on suspension component mountings and holed inner wings compromised structural integrity. Although the vehicle has passed subsequent tests, the sheer volume of corroded components indicates that the underlying issue of oxidation is widespread and not being resolved. The recorded mileage of 106,484 miles over approximately 19 years averages roughly 5,600 miles per year. This low annual usage suggests the vehicle has not been subjected to heavy long-distance driving, which may explain the relatively low wear on mechanical drivetrain components. However, the data shows consistent annual testing, with mileage increasing by approximately 3,000 to 4,000 miles between each inspection. The lack of heavy mileage accumulation often correlates with vehicles that spend significant time stationary, which can accelerate the surface and structural corrosion noted in the MOT history. A prospective buyer must prioritise a thorough underside inspection to assess the severity of the rust. The records from December 2023 and December 2024 specifically highlight corrosion on the chassis legs, sills, floor, and fuel pipes. Because the tester flagged the nearside rear seat belt anchorage as corroded in December 2024, the structural integrity of the passenger cell requires careful scrutiny. The recurring mention of corroded suspension arms and strut top mountings suggests that many of these components may soon require replacement to maintain roadworthiness. Mechanical attention should also be directed toward the braking system and steering. The December 2023 record noted a binding nearside rear service brake, and the December 2024 test identified a damaged offside front track rod end dust cover. While these may appear as minor consumable issues, they are part of a broader pattern of aging components. Given the history of brake pipe corrosion, a physical check of the hydraulic lines is essential to ensure no leaks or thinning of the metal are present.
