Porsche 911 (2008)
2008 Porsche 911
CarHunch analysed 2,249 real MOT records for the 2008 Porsche 911. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
The 2008 Porsche 911 passes its MOT first time at 89.5%, well above the UK average of 80%, which signals solid overall reliability for a 16-year-old sports car. However, one in five of these vehicles has recorded a dangerous defect at some point, so mechanical inspections and service history matter significantly when buying.
With a median mileage of just 39,141 miles, these 911s are typically low-mileage enthusiast cars, and they average 1.63 failures per test, suggesting wear items rather than structural problems. Before purchase, obtain a full service history and have a Porsche specialist inspect the brakes, suspension, and cooling system—the 9.5 advisories per vehicle indicate these systems need regular attention.
What to check before buying a 2008 Porsche 911
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.
- ⚠️ 20.3% 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.
