The 2003 Vauxhall Signum is a genuinely risky proposition: its 69.5% first-time pass rate sits 10.5 points below the UK average, and a concerning 33.6% of these cars have recorded a dangerous defect at some point. Both petrol and diesel variants fail at identical rates, so fuel choice won't improve your odds here.

These Signums are averaging 83,645 miles at test, which is reasonable for their age, but they're racking up 4.5 failures and over 20 advisories per vehicle on average—well above what you'd expect from a reliable buy. Before committing to one, have a pre-purchase inspection done by someone who knows Vauxhalls well, and factor in the likelihood of significant repair bills ahead.

For context

⚠️ Below average. More vehicles in this cohort fail their first MOT than typical. Scrutinise this vehicle's history — look for recurring issues, not just the latest result.

🔧 Expect consumable spend. An average of 20.5 advisories per vehicle tells you wear items (tyres, brakes) get flagged regularly. Budget for them — they're not surprises.

🔍 The dangerous defect figure is real. Most are one-off tyre failures or brake issues — not structural problems. But it's exactly why checking the individual vehicle's history is essential, not optional.

These stats describe 2,748 vehicles as a group. The specific vehicle you're looking at could be the one good example or the one outlier. Run its registration to find out.
