2018 Mini Mini (r57)
CarHunch analysed 248 real MOT records for the 2018 Mini Mini (r57). This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
The 2018 MINI MINI (R57) passes its MOT first time at 86.7%, a solid 6.7 percentage points above the UK average—but the 43.5% dangerous defect rate is a serious red flag that suggests structural, brake, or steering issues are common in this cohort and warrant professional inspection before purchase. This is a car with genuine reliability strengths, yet nearly half of examples tested have harboured defects serious enough to fail an MOT.
At 20,289 miles median, these cars are relatively lightly used for their age, which makes the high dangerous defect prevalence even more concerning—it points to design or build quality rather than wear and tear. Budget for an average of 0.95 failures and 3.3 advisories per MOT cycle, and ask your mechanic to specifically check suspension geometry, brake condition, and any welding repairs before committing to a purchase.
What to check before buying a 2018 Mini Mini (r57)
