2009 Vauxhall Insignia 2.0L Diesel · ST59 BKK

The vehicle remains roadworthy but the maintenance history indicates a stable trend of structural degradation and deferred consumable upkeep. The most recent test in June 2024 at 148,001 miles resulted in a pass, though the tester flagged a nearside rear tyre reaching the legal limit. While the car has passed its annual inspections, the recurring presence of corrosion and tyre wear issues suggests a vehicle that is entering a stage of its life where structural integrity will require closer monitoring. At 17 years old, the recorded mileage of 148,001 miles represents an average usage of approximately 8,700 miles per year, which aligns with typical national averages. The data shows consistent use over time, with roughly 8,000 miles covered between the June 2023 and June 2024 tests, and similar intervals noted in the four years prior. This steady accumulation suggests the vehicle has not suffered from long periods of standing, but the high total mileage combined with its age puts significant stress on rubber components and metal brackets. A buyer must prioritise a thorough underbody inspection focusing on the rear subframe and suspension mounting points. Records from 2022 and 2023 explicitly noted corrosion on the subframe and mounting areas, and while these were not classified as seriously weakened at the time, rust on these Vauxhall components often progresses rapidly once it takes hold. The offside rear fuel pipes flagged in 2023 also require a physical check for brittleness or surface scaling, as fuel-related corrosion presents a specific safety risk. Mechanical attention should also be paid to the central front oil leak. Its presence noted in 2020 at 112,828 miles and again in 2023 at 136,471 miles indicates a persistent leak that may stem from a weeping gasket or oil seal failure. Furthermore, the frequent reports of tyres worn to the edge across multiple years suggest a potential issue with alignment or worn suspension bushes that should be verified during a road test to prevent further premature tyre failure.
