You'll be able to fit in everything from double prams to kids bikes. And then there are those two seats in the boot which easily pull up and lock into place. With the two seats up, the boot space shrinks dramatically, but you'll still be able to fit school bags or groceries.
However, space in the third row is tight, there are no two ways about it. I'm 161cm and could just get my legs in. However, the middle row moves forward so you'll be able to give back row passengers more room.
Kids will be fine in here but adults will be hankering to climb out. This is why it probably won't be used as a seven-seater full-time, unless all of your kids are little. It works really well as a five seat SUV, popping up the spare two seats when you really need them.
The middle row has plenty of space, my two children aged five and seven were very happy over the whole week of shopping for My Little Pony paraphernalia, even with the second row moved forward to give the back row more leg space.
And the front was very airy and breezy for both my 185cm husband and myself. We had lots of leg and head space, there wasn't a complaint to be had.
