Mini Cooper S (2015)
2015 Mini Cooper S
CarHunch analysed 8,049 real MOT records for the 2015 Mini Cooper S. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
The 2015 MINI Cooper S passes its MOT at 87%, comfortably above the UK average of 80%, but nearly a third of these cars have recorded a dangerous defect at some point—a significantly higher concern rate that buyers should take seriously. Petrol and diesel variants perform nearly identically, both around 87%, so fuel type isn't a reliability differentiator here.
At under 45,000 miles on average, these are relatively low-mileage examples, yet they're accumulating 7 advisories per car on test, suggesting age-related wear (suspension, trim, minor electrics) rather than major defects. With 1.24 failures per vehicle and a median carhunch score of 50, expect to budget for routine maintenance—get a pre-purchase inspection that specifically flags any history of electrical gremlins or suspension issues common to this generation.
What to check before buying a 2015 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.
- ⚠️ 31.4% 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.
