The 2004 MINI Cooper S has a first-time pass rate of 75.8%, slightly below the UK average of 80%, and nearly half of these cars (45.5%) have experienced a dangerous defect at some point—a significant concern for a buyer. This suggests the model carries inherent reliability challenges beyond typical wear-and-tear issues.

At 70,480 miles on average, these cars are reasonably well-preserved for their age, yet they're still racking up 5.37 failures and 38.6 advisories per test, pointing to chronic minor issues rather than catastrophic breakdowns. If you're considering one, budget for regular maintenance and have a pre-purchase inspection focus on brake and suspension components—the high dangerous defect rate suggests those areas warrant close scrutiny.

We have limited data for the 2004 Mini Cooper S — treat the figures below as indicative rather than definitive.

⚠️ 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.
