Vauxhall Signum (2003-2009)

Vauxhall's replacement for the Omega was based on the Vectra, so it didn't win many fans as it was seen as an overpriced family hatch rather than a distinct model worth a premium. That's good news for used buyers; the Signum's lack of visibility has ensured that residuals are less than rock solid. However, with a high specification, practicality galore and a decent choice of engines, the Signum has a lot to offer.

Vauxhall Signum (2003-2008) Checklist

  • On the 2.2 turbodiesel, the engine's timing chain pulley can fail - but there's no warning of the impending disaster.
  • With the 1.9CDTi engine, power can be lost when the throttle butterflies seize up. It's an easy fix, but is involved.
  • Most Signums are gadget-laden, so check that everything works - especially xenon lights, sat-nav systems and the alarm.
  • Many Signums have over-sized alloy wheels, easily kerbed and which can destroy the ride. It's best to stick with wheels no bigger than 17 inches across.
