VAUXHALL SIGNUM2006 · 3.0L DIESEL

The vehicle presents a questionable roadworthiness profile due to a significant lack of testing over the last seven years. The last recorded test in August 2019 at 94,067 miles resulted in a pass with advisories for worn rear brake discs. Because no MOT has been performed since mid-2019, the current mechanical and safety integrity of the vehicle remains unverified. The maintenance trend appears stagnant, as the car has sat without official certification for an extended period which often leads to rubber degradation and fluid ingress. The mileage data is highly inconsistent and suggests potential irregularities. The vehicle recorded 140,928 miles in August 2018, yet it showed only 94,067 miles in August 2019. This impossible reduction of 46,861 miles within a single year indicates either serious clerical entry errors or a cluster replacement. While the overall average of roughly 4,700 miles per year is low for a twenty-year-old car, the specific drop between 2018 and 2019 renders the recorded distance unreliable for assessing. A buyer must conduct a thorough physical inspection of the suspension and exhaust systems. The 2019 failure highlighted multiple critical issues including a major exhaust leak, a defective central mounting, and a perished anti-roll bar linkage. Given the long gap in testing, the inspector should check for structural corrosion on the exhaust hangers and perished bushings in the Macpherson strut assemblies. The history of inner-edge tyre wear and misalignment also suggests alignment issues that may have persisted if not properly addressed. Attention is also required for the engine management indicator light, which was flagged as inoperative in 2019, to ensure the management system has not been bypassed or left faulty.
