2018 Vauxhall Insignia 1.6L Diesel · FN68 OGL

The Vauxhall Insignia presents a broadly roadworthy picture, with the most recent test on 25 September 2023 at 58,214 miles returning a pass after an initial failure on the same day that recorded no defects. The maintenance trend is stable across the available history, showing no escalating mechanical faults or recurring advisory items. The paired fail and pass entries on identical dates and mileages suggest administrative or presentation anomalies at the test centre rather than genuine roadworthiness defects. Annual mileage sits at roughly 7,277 miles per year against an eight-year lifespan, which is typical for the vehicle's age and points to moderate use. The record jumps from 37,291 miles at the 17 September 2021 test to 47,653 miles by 21 September 2022, then to 58,214 miles by 25 September 2023, equating to about 10,000 miles per year across those two years and a slight uplift from the longer-term average. No long dormant periods or abrupt accumulation spikes are evident, and the clean defect sheets across all five entries indicate the previous keeper kept basic statutory testing in order. A buyer should still commission a physical inspection despite the absent advisories. The 2022 and 2023 tests both logged fails with zero defects recorded, so verify the V5C and DVSA portal to confirm those were clerical reversals and not suppressed corrosion or emissions faults. With no suspension bushes, coil springs, brake discs, or structural integrity issues ever flagged, the chassis and running gear show no documented wear trend, but eight years of use warrants checking for underbody rust and tired consumables such as tyres and wiper blades that a pass does not exempt. Given the last test dated over two years before today's review, the Insignia is now due a fresh MOT and may have covered little distance since 2023. Treat the clean history as a positive baseline rather than a guarantee, and prioritise a pre-purchase mechanical check on brakes, suspension joints, and exhaust emissions before committing.
