Should I check the MOT history before buying a 2008 Vauxhall Signum?

Yes. Look for recurring advisories — slow-building issues like corrosion or brake wear patterns show up years before they become failures. A full MOT history analysis will highlight patterns that a single test result won't reveal.

Check brake pipes, sills, subframes, and chassis legs. Surface rust is normal at this age; structural rust is a serious problem that is expensive to fix and can fail an MOT.

The 2008 Vauxhall Signum falls noticeably short of the UK average with a 72.7% first-time pass rate against the 80% benchmark, and that's a genuine concern for reliability. More alarming is that half of these cars have recorded a dangerous defect at some point—well above acceptable—which makes pre-purchase inspection non-negotiable if you're seriously considering one.

With 91,050 miles as the average, these Signums have covered reasonable ground for their age, yet they're still racking up 4.16 failures per test on average. The high advisory count of 21.4 per vehicle suggests ongoing wear and small issues that accumulate; get a full pre-purchase inspection including brakes, suspension, and lights, and budget for near-term remedial work once you own it.

We have limited data for the 2008 Vauxhall Signum — treat the figures below as indicative rather than definitive.

⚠️ Over 1 in 5 of these vehicles have had a dangerous MOT failure at some point — usually tyres or brakes, and often a one-off issue rather than a persistent problem. The group stats won't tell you which one you're looking at.
