MINI 3DR HATCHBACK II (2018-21) 3DR HATCHBACK II 1.5 102 SS EU6 ONE 6SPD
Buyer's Guide & Data from our Checks
The MINI 3DR HATCHBACK II (2018-21) 3DR HATCHBACK II 1.5 102 SS EU6 ONE 6SPD is a small, three-door hatchback with premium styling and a city-friendly footprint. In the UK market, it sits above basic runabouts for image and cabin finish, while remaining more compact and playful than family-focused hatchbacks.
Its 1.5-litre petrol engine and six-speed manual suit commuting, errands and weekend trips, especially for singles, couples or first-time buyers. Rear seats and boot are less accommodating than in five-door rivals, making it best for occasional passengers rather than growing families; its lively, precise feel is a key appeal here.
