We’ll start in the third row, because that’s essentially the reason you’re looking at a Santa Fe. And the space is good. My two little ones insisted on sitting in the third row the whole week, purely for novelty factor! They had enough space of course, being aged four and six.
I had enough room in there too, at 161cm, but take note, there is a limited amount of leg space (the kids loved it because they could actually reach the toys they dropped without yelling out to me all the way down the front). You can move the middle row forward to give back passengers more leg space if necessary, however.
The second row has loads of room for the children, and you can fit a third child seat in the middle, too. My two had space galore to themselves and were climbing all over this car in absolute merriment (and monkey-ness. Yours too?). Even with this row pushed forward to allow more space for the back, I was able to fit comfortably with enough space in between my knees and the front seat.
Both my 185cm husband and I fit very comfortably in the front, him in his long-legged driving position and me in my short one! There’s also a good amount of space between the passenger seat and driver’s seat so you never feel cramped, and even with the sunroof there is a lot of headspace.
The boot is a good size, too. With five seats in use (so, the last row down flat), you’ll get 547 litres which will just about fit most things a family needs. It’s so big you’ll need to climb in there if you want to do a tether point up on the kids’ car seats.
With all seven seats in use, the bootspace shrinks, but I was still able to fit two scooters and two helmets in there, and you can get school bags in or some grocery bags. Nothing big though, so you’ll definitely get very good at fastening luggage to the roof if you like going on long trips and you have a bigger family. This is nothing new in seven seaters - most don’t have ample boot space when all seven seats are in use. It’s just the nature of the seven-seat SUV.
