Across 2,863 MOT tests of the MINI Convertible in the DfT's 2023 MOT data (initial tests, retests excluded), 29.9% failed — about 1 in 3. The parts that fail most are lights and electrics (15.4% of tests), tyres (7.9%), brakes (5.5%), wipers, windscreen and mirrors (5.0%) and suspension (4.8%).
Allowing for age and mileage, the MINI Convertible has 12% fewer MOT failures than the average car of the same age and mileage.
This is a small sample of tests, so treat the percentages as rough.
The MOT checks safety and emissions items — brakes, suspension, steering, lights, tyres, body structure and exhaust emissions. It does not test engines, gearboxes or most electronics, so those faults only show up here when they cause an emissions failure or a leak.
