The VAUXHALL SIGNUM (2003-08) 5DR HATCHBACK 3.0 V6 CDTI ELITE is a large, five-door diesel hatchback with a more spacious, upmarket feel than an ordinary family car. In the UK, it sits between mainstream hatchbacks and executive models, offering an alternative to a Ford Mondeo or Volkswagen Passat for buyers wanting something less common. Its roomy cabin and generous rear-seat space make the Signum suitable for families, business users and regular long-distance commuters. The 3.0-litre V6 diesel is best appreciated by drivers seeking relaxed, strong performance on faster roads, rather than low-cost town motoring. Compared with familiar family rivals, its distinctive design and less common presence are its main talking points.
