2015 Vauxhall Insignia 2.0L Diesel · AE15 HFW

The vehicle remains technically roadworthy but the mechanical condition shows a worsening trend regarding structural corrosion and suspension wear. The most recent test in July 2025 at 111,841 miles identified new issues including deteriorated rear bump stops and corrosion on the rear shock absorber casings. While the vehicle passed, the persistent presence of corrosion on the rear sub-frame, which has been noted in every test since 2023, indicates an ongoing process of oxidation that has not been addressed by the previous owner. At 111,841 miles, the Insignia has averaged approximately 10,000 miles per year, which aligns perfectly with typical UK usage for an 11-year-old vehicle. The record shows consistent usage patterns, with roughly 14,000 miles covered between the 2024 and 2025 tests, and another 12,000 miles in the preceding year. This steady accumulation suggests the car has been used regularly, which generally benefits components better than a vehicle left standing for long periods. A buyer must conduct a thorough physical inspection of the rear sub-frame and suspension arms to determine the depth of the rust. The tester flagged uneven inner wear on the rear tyres in 2024 at 97,762 miles, suggesting an alignment issue caused by the corroded suspension arms and toe links. Given the history of thin brake pads and worn discs recorded in 2022, the entire braking system should be checked for uneven thickness or seized calipers. The persistent damage to the central windscreen noted in the two most recent tests should also be monitored for spreading cracks that could eventually compromise the driver's view.
