About the 2018 Mini Cooper S
With an overall Carivo score of 7.0/10, the 2018 Mini Cooper S earns a Good rating among the hatchbacks we've scored. Its strongest dimension is Performance at 7.4/10. It's a capable but unexceptional hatchback — stronger alternatives exist if you're willing to shop the segment carefully.
Reliability and safety are the two dimensions that matter most for long-term ownership costs. We rate reliability at 6.7/10 — below the segment average in our scoring. Budget for potentially higher maintenance costs and check the recall record below before buying. On safety it earns 7.2/10: respectable, if not class-leading — several competitors bundle more driver-assist tech as standard. Check your trim's official ratings at nhtsa.gov.
Performance lands mid-pack at 7.4/10: enough power and composure for everyday needs, without the dynamics that distinguish the segment's driver-focused options. Technology comes in at 7.3/10 — functional and modern, with wireless connectivity and core ADAS features, though some competitors pack more standard tech at this price point.
Priced from $30,253–$36,533, 24 MPG, seating 4, the Mini Cooper S sits in the mid-market bracket of the hatchback segment. The value score of 6.6/10 is a red flag — comparable alternatives offer meaningfully more for the same outlay. Shop the segment before deciding. At 8 years old, resale value, parts availability, and whether a successor model has improved on its weak points are all worth investigating before committing.
Bottom line: There's a case for the 2018 Mini Cooper S, but it needs the right buyer. Its reliability and value scores trail the class, and several higher-rated rivals sell for similar money — comparison-shop before committing.
