2011 Vauxhall Insignia 2.0L Diesel · EY11 UNG

The vehicle remains roadworthy, but the maintenance trend shows a concerning shift toward structural degradation. While the most recent test in October 2025 at 128,986 miles passed, the tester specifically flagged corrosion on the rear sub-frame. Although the rust was classified as not seriously weakened at that stage, it marks the beginning of a potential structural issue that contrasts with the three-year period of clean records seen between 2022 and 2024. The mileage pattern is consistent with typical use for this age, averaging approximately 8,600 miles per year. Between October 2021 and October 2025, the vehicle covered 19,861 miles, representing a steady usage of roughly 5,000 miles annually. This low annual mileage suggests the car was not subjected to high motorway stress, yet the 2021 advisory regarding perished rear tyres at 109,125 miles indicates the vehicle may have sat for extended periods, leading to rubber degradation despite the low tread wear. A buyer must prioritize a physical inspection of the rear sub-frame to determine if the corrosion has progressed since the October 2025 advisory. Given the Insignia's history with rust issues in specific areas, you should check for flaking metal or thinning material that could lead to a structural failure. The previous failure of perished tyres necessitates a thorough check of all tyre sidewalls for cracking or bulging to ensure the low mileage has not masked age-related rubber failure.
