Background

The Opel Signum is a large front-engine, front-wheel drive, five-passenger, mid-size executive hatchback manufactured and marketed by the German car manufacturer Opel from 2003 to 2008, exclusively over a single generation, derived from the Opel Vectra. Marketed almost exclusively in Europe, a rebadged Signum was marketed in the United Kingdom as the Vauxhall Signum. The Signum used the long wheelbase version of the GM Epsilon platform also used by the Opel Vectra Caravan.
