Vauxhall Omega (1999)
1999 Vauxhall Omega
CarHunch analysed 12,675 real MOT records for the 1999 Vauxhall Omega. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
The 1999 Vauxhall Omega has a 70.1% first-time pass rate, sitting 10 percentage points below the UK average of 80%—a meaningful reliability gap for a vehicle now 25 years old. Nearly one in five of these cars (18.9%) have recorded a dangerous defect during their MOT history, which is a genuine concern if you're considering one as a regular driver.
These Omegas are running at typical mileage for their age (median 103,539 miles), but they're accumulating serious faults: the average car has failed twice and racked up 8.2 advisories, suggesting widespread wear across multiple systems rather than isolated problems. If you buy one, budget for a full pre-purchase inspection covering suspension, brakes, and lights—and treat any with a dangerous defect history as a non-starter.
What to check before buying a 1999 Vauxhall Omega
Practical pre-purchase checks for this age and model.
- 📋 Check the full MOT history. Look for recurring advisories — slow-building issues like corrosion or brake wear patterns show up years before they become failures. Enter the reg below for a full AI analysis.
- 🔍 Inspect for corrosion in person. Brake pipes, sills, subframes, and chassis legs. Surface rust is normal at this age; structural rust is a serious problem that's expensive to fix and can fail an MOT.
- 🛞 Check tyres and brakes. The most common advisory items at this age. Budget for replacement if they're near the limit — factor this into your offer price.
- 📄 Run an HPI check. The MOT history won't show outstanding finance, insurance write-offs, or stolen status — an HPI check will.
