Every Vauxhall Signum model year

Pass rates fall as cars age, so the only fair comparison for a 2006 car is other cars of the same age. The full run for the Vauxhall Signum:

What this means if you are buying a 2006 Signum

The 2006 is one of the stronger years for this model, passing 4 points more often than the Vauxhall Signum average. That is a point in its favour, though condition and service history still matter more than the model year.

What a 20-year-old car fails on

A 2006 car is 20 years old now, and age drives the failure mix more than the badge does. Across all cars tested, these are the categories that actually cause failures:

  • Lights and electrical: 10.36% of all cars tested
  • Suspension: 8.65% of all cars tested
  • Tyres: 6.23% of all cars tested
  • Brakes: 6.1% of all cars tested
  • Visibility: wipers, washers, glass: 4.65% of all cars tested
  • Body, chassis and structure: 3.18% of all cars tested

That is high mileage, so timing belts, clutches, suspension bushes and corrosion are the items worth budgeting for rather than the MOT itself. On a 2006 Vauxhall Signum the average at test was 123,837 miles, so treat anything far above that as a car that has worked harder than its peers, and anything far below as one worth checking for the faults that come from standing still.

2006 is the strongest year on record for this model at 66.3%, ahead of every other year we hold data for.
