2008 Saab 9 3

CarHunch analysed 12,764 real MOT records for the 2008 Saab 9 3. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.

The 2008 SAAB 9-3 falls short of the UK average with a 76.9% pass rate, and that's concerning given that 41.5% of these cars have recorded at least one dangerous defect during their MOT history—well above acceptable. Diesel versions perform slightly worse at 76.4% pass rate compared to petrol at 78.5%, though neither inspires confidence.

At 90,645 miles average, these 9-3s are running higher mileage than typical for a 2008, which explains why they average 3.69 failures and a hefty 18.7 advisories per test. Before buying one, get a pre-purchase inspection focusing on the suspension, braking system, and electrical components—the advisory count suggests wear-and-tear issues are widespread rather than isolated to a few bad examples.

What to check before buying a 2008 Saab 9 3

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.
  • ⚠️ 41.5% of these vehicles have had a dangerous defect recorded. Enter the reg below — the full MOT history will show exactly what was flagged and whether it was resolved.
  • 📄 Run an HPI check. The MOT history won't show outstanding finance, insurance write-offs, or stolen status — an HPI check will.
