MG 6 (2012)
2012 MG 6
CarHunch analysed 641 real MOT records for the 2012 MG 6. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
The 2012 MG 6 falls short of the UK average with a 75.9% first-time pass rate, and that's a significant concern—nearly half of these cars (46.5%) have recorded dangerous defects during their MOT history, which is well above acceptable levels for a buyer evaluating safety. This suggests systematic issues beyond minor wear and tear.
At 53,900 miles median, these cars are running relatively low mileage for their age, yet they're averaging 3.11 failures and 19.5 advisories per test, pointing to underlying build or component quality problems rather than just age-related degradation. If you're considering one, budget for repairs and insist on a full MOT history check before purchase—the high dangerous defect rate makes this model riskier than most alternatives in its class.
What to check before buying a 2012 MG 6
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.
- ⚠️ 46.5% 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.
