BMW M6 (2005)

338 real MOT outcomes analysed • 81.7% first-time pass rate

2005 BMW M6

CarHunch analysed 338 real MOT records for the 2005 BMW M6. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.

The 2005 BMW M6 passes its MOT at 81.7%, marginally above the UK average of 80%, but one in five have recorded a dangerous defect at some point—a notable concern for a high-performance machine that demands close inspection before purchase. These are relatively low-mileage examples with a median of just 54,393 miles, suggesting they've been cherished rather than thrashed, yet they still average nearly two failures per test.

The 12.3 advisories per vehicle reveal these ageing V10 coupes need consistent attention to stay roadworthy, with electrical and suspension items typically accumulating minor issues. If you're considering one, insist on a pre-purchase inspection from a BMW specialist and budget for regular maintenance—the pass rate is decent, but the failure and defect patterns mean neglected examples will disappoint quickly.

What to check before buying a 2005 BMW M6

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.
  • ⚠️ 21% 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.
