Mini offers a reasonably priced sliding rear bench as an option on all but the Cooper SE model. Like similar systems on rival SUVs, this allows you to slide the seats forward to prioritise boot space or backwards to give your passengers more rear leg room. With the seats farthest forward, only very young children will be comfortable, although you do get plenty of room for adults with them slid back. The Cooper SE gets slightly less rear head room as a result of the battery pack under the back seat, but you’re unlikely to notice. Only if you have a six-foot-plus driver might you struggle to get another similarly tall adult in the back.
The additional width of the second-generation car makes squeezing three across the rear bench a little easier, but it’ll still be rather cosy. For similar money, you could have an even larger SUV that will make carrying lofty individuals easier. Isofix child seat mountings are standard for the outer two seats but a centre armrest is an optional extra. The door pockets could be a little bigger, too. Access isn’t too tricky, though, due to bigger rear door openings, but you will have to duck down more than in taller rivals.
