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.

The 2015 Mini Cooper S has a decent first-time pass rate (87.7%), but a higher-than-average share of vehicles have had serious defects recorded — the individual vehicle's history matters a lot here.

⚠️ Over 1 in 5 of these vehicles have had a dangerous MOT failure at some point — usually tyres or brakes, and often a one-off issue rather than a persistent problem. The group stats won't tell you which one you're looking at.

For context
Good baseline reliability. A 87.7% first-time pass rate puts this well above the UK average — it's a well-sorted vehicle in this age bracket.
🔧 Expect consumable spend. An average of 7 advisories per vehicle tells you wear items (tyres, brakes) get flagged regularly. Budget for them — they're not surprises.
🔍 The dangerous defect figure is real. Most are one-off tyre failures or brake issues — not structural problems. But it's exactly why checking the individual vehicle's history is essential, not optional.

These stats describe 8,049 vehicles as a group. The specific vehicle you're looking at could be the one good example or the one outlier. Run its registration to find out.

28,786–50,278 miles — normal for age. This is where most 2015 Mini Cooper Ss sit.
Over 67,875 miles — higher than typical. Not necessarily a problem, but check service history and look out for advisory build-up on tyres and brakes.

Strong survival — 7,491 vehicles still getting MOTs in 2025, 98% of the peak.

Based on vehicles from this manufacture year that had at least one MOT test in each calendar year. Data from 2018–2025.
