Should I check the MOT history before buying a 2004 Vauxhall Omega?

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.

What corrosion should I look for when inspecting a 2004 Vauxhall Omega?

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.

Tyres and brakes are the most common advisory items on vehicles of this age. Budget for replacement if they are near the limit, and factor this into your offer price.

The 2004 Vauxhall Omega falls short of the UK average by 4.2 percentage points, with a 75.8% first-time pass rate, and a quarter of these vehicles have recorded dangerous defects at some point—a higher proportion than you'd want to see in a car of this age. The petrol variants (which make up nearly all of the sample) show no material difference, passing at 75.7%, so fuel type isn't a distinguishing factor here.

These Omegas are averaging 76,500 miles, which is reasonable for a 20-year-old car, but the real concern is the failure pattern: 3.24 failures per vehicle and nearly 20 advisories suggests cumulative wear and corrosion catching up with the model. If you're considering one, budget for imminent repairs and insist on a pre-purchase inspection focusing on brakes, suspension, and rust—don't rely on a recent pass alone.

We have limited data for the 2004 Vauxhall Omega — 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.
