BMW M5 (2005)
2005 BMW M5
CarHunch analysed 754 real MOT records for the 2005 BMW M5. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
The 2005 BMW M5 just edges ahead of the UK average with an 81.4% first-time pass rate, though one in five of these cars have recorded a dangerous defect during their MOT history—a notable concern for a performance car of this age. The petrol engines achieve an 81.0% pass rate, which is solid and consistent with the overall cohort.
These M5s are running at a sensible 65,397 miles on average, suggesting careful ownership, but the 10.9 advisories per vehicle and 1.9 failures per test reveal that running costs and maintenance demands are steep. Before committing to one, factor in that you're buying a high-specification performance engine; get a pre-purchase inspection from an M-car specialist and budget generously for repairs, particularly around the engine bay and braking system.
What to check before buying a 2005 BMW M5
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.
- ⚠️ 20.4% 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.
