That's 8 points below the average of 82% across all models in our data, so check the year-by-year data carefully before buying. Our records list diesel and petrol versions.

Best and Worst Years

Of the years with at least 100 tests, the 2001 model has the highest pass rate at 79% from 387 tests. The 2002 model has the lowest at 70%. The 9 point gap means pass rates vary somewhat between years, but no year is dramatically different. Newer cars usually pass more often simply because they are younger.

Mileage Across Years

The oldest model in our data (1995) averages 127,436 miles, while the newest (2004) averages 89,855 miles. Older models have covered serious mileage, so suspension and drivetrain wear are worth checking.

Compared to the Vauxhall brand average of 84%, the Omega is 10 points lower, placing it among the less reliable Vauxhall models.
