Mini Cooper S (2012)
2012 Mini Cooper S
CarHunch analysed 1,309 real MOT records for the 2012 Mini Cooper S. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
The 2012 MINI Cooper S passes its MOT slightly above the UK average at 83.3%, which is reassuring—but the 32.3% dangerous defect rate is a serious red flag that suggests electrical, brake, or suspension issues crop up regularly in this cohort. For a 12-year-old car, the median mileage of 46,400 is reasonable and not excessively worn, though the average of 1.98 failures per test indicates these cars do develop faults that need fixing between passes.
The 11.3 advisories per vehicle suggest ongoing wear typical of the age and marque, but the high proportion of cars ever experiencing a dangerous defect means you should budget for potential safety-critical repairs and have any purchase inspected by a specialist who knows the Cooper S's weak spots. Before committing, request the full MOT history and get a pre-purchase inspection focused on braking, electrical systems, and suspension components.
What to check before buying a 2012 Mini Cooper S
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.
- ⚠️ 32.3% 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.
- 📄 Run an HPI check. The MOT history won't show outstanding finance, insurance write-offs, or stolen status — an HPI check will.
