2016 Vauxhall Insignia 1.6L Diesel · FN66 NCC

The vehicle presents a stable and highly positive maintenance trend, culminating in a clean pass at its most recent test. On 17 March 2026 at 108,461 miles, the Insignia passed with zero defects. The record shows a failure on the preceding day at the identical mileage with no defects documented, indicating an administrative anomaly or an aborted test rather than a mechanical fault. The subsequent pass confirms the car met all roadworthiness standards. This unblemished record implies a fastidious approach to vehicle upkeep, with no recurring mechanical or structural issues flagged over the last three years. The mileage accumulation aligns with low-mileage usage for a vehicle of this age. Between the February 2023 test at 100,302 miles and the March 2026 test at 108,461 miles, the Insignia covered 8,159 miles over 36 months, averaging roughly 2,720 miles per year. The annual intervals prior—March 2024 at 103,545 miles and March 2025 at 106,403 miles—show increments of roughly 2,800 to 3,000 miles. This low annual mileage suggests the vehicle spent significant periods stationary or was used exclusively for short, local journeys. Such usage patterns often mask underlying issues, as short runs prevent the engine and exhaust from reaching optimal operating temperatures, potentially leading to moisture buildup and premature wear of consumables. Despite the pristine MOT history, a buyer must physically inspect components that typically degrade on a decade-old Vauxhall Insignia, even when paperwork remains clean. The absence of advisories does not guarantee the absence of wear. Focus on the suspension and drivetrain; check for perished suspension bushes, leaking shock absorbers, and worn drop links, which commonly deteriorate on vehicles covering low annual mileages due to static load and age-related rubber decay. Inspect the brake discs and pads for lipping and corrosion, as infrequent use often causes surface rust that the MOT tester might not classify as a dangerous defect. Examine the exhaust system for signs of corrosion or weak spots, particularly around the flexi-joint and silencer seams. Finally, scrutinise the tyre sidewalls for cracking, as older tyres with adequate tread can still pose a structural risk.
