2006 Vauxhall Signum 2.2L Petrol · KS56 AEU

This Vauxhall Signum presents an unusually clean MOT history, with no defects recorded across five consecutive tests spanning from October 2022 to October 2025. The most recent entries—both a pass and a fail on the same day in October 2025—are puzzlingly devoid of any advisories or defects, which is highly unusual for a vehicle of this age and mileage. The fail itself appears administrative rather than mechanical, given the identical mileage readings (44,512 and 44,516 miles) and the absence of any recorded issues. This suggests either a clerical error or an exceptionally well-maintained example, though the lack of advisories over three years raises questions about whether minor wear items (such as tyres, wipers, or bulbs) were addressed outside the MOT framework. The trend is stable in the absence of defects, but the absence of advisories is a red flag—either the car has been meticulously serviced, or critical checks have been overlooked. The mileage accumulation is strikingly low for a 20-year-old vehicle, averaging just over 2,200 miles per year. Over the past three years, the Signum has covered only 5,906 miles (from 38,611 in 2022 to 44,516 in 2025), indicating either infrequent use or prolonged periods of inactivity. The consistency in mileage increments—approximately 1,970 miles annually—suggests the car has not been subject to seasonal fluctuations or heavy usage. Such low mileage reduces wear on drivetrain components, suspension, and brakes, but it also raises concerns about fluid degradation (oils, coolants, brake fluid) and potential corrosion from prolonged exposure to moisture. The lack of mileage variation makes it difficult to assess whether the vehicle has been driven regularly enough to prevent issues like seized bearings or stiff suspension bushes. Given the absence of recorded defects, a buyer should prioritise a thorough inspection of components typically overlooked in MOT tests. Focus on the suspension—check for worn or perished bushes, degraded coil springs, and signs of leakage in dampers, particularly since low mileage can mask early wear. Inspect the brakes for uneven wear on discs and pads, as binding calipers or seized wheel bearings often go unnoticed without dynamic testing. Examine the underbody for structural corrosion, especially around wheel arches, sills, and exhaust mounts, given the car’s age and potential for prolonged standing. Fluid levels and condition (engine oil, brake fluid, coolant) should be verified, as stagnant fluids degrade over time. Finally, test all electrical systems, including lights, sensors, and the infotainment display, as intermittent faults may not trigger MOT advisories but could indicate deeper wiring or module issues. The clean MOT record is compelling, but the lack of advisories over three years is atypical and warrants caution. A buyer should treat this as an opportunity to conduct a pre-purchase inspection with a specialist, particularly given the car’s low mileage and the unusual absence of even minor wear items in the history. The Signum may well be in excellent condition, but the data suggests either exceptional maintenance or significant gaps in routine checks.
