A bold move of Vauxhall-Opel to maneuver its traditional large sedan buyers right into a crossover vehicle is proving an uphill struggle; the marketplace sector is deeply conservative.

However those who’ve taken the plunge happen to be satisfied with your decision; Signum is a highly competent package, with a lot of interior space along with a range of drive train options which cover all required bases.

The 2.0 litre petrol-engined model feels just a little flat – there is lots of bodywork to become hauled about with a small engine – however the 3.0CTDi is great fun, with waves of torque. Handling is neat and precise; the only real weakness is steering that feels just a little remote.

There’s been some criticism how the Signum is not sufficiently distinct to look at to the Vectra estate. Overcome that, though, and you’re simply dealing with a competent and effective car for the executive buyer.
