The 2021 MINI John Cooper Works is a genuinely reliable performer, with a 93.3% first-time pass rate that sits well above the UK average of 80%—and only 9.9% of vehicles have ever recorded a dangerous defect, which is reassuringly low. This is a petrol-only model, so there's no fuel-type trade-off to consider.

At 22,175 miles median, these cars are running low mileage for their age, which partly explains the strong pass rate and the modest 0.22 failures per vehicle on average. The 1.2 advisories per car suggest minor wear items are beginning to show, but if you're shopping for one, a pre-purchase inspection focused on brake wear and suspension will catch any real problems before they escalate.

The 2021 Mini John Cooper Works passes its MOT first time more often than most UK vehicles (93.4% vs ~80% average) — and when it does fail, it's usually something minor and cheap to fix.

⚠️ About 1 in 12 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 93.4% first-time pass rate puts this well above the UK average — it's a well-sorted vehicle in this age bracket.
🔍 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 2,517 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.
