Iso fix is overrated. And is not necessary. Even isofox car seats have the option of securing with a three point belt. The reason for wanting a station wagon is for the three point belt position.
I completely agree and that is how I grewnup And have no issue with it. The problem Is the when big enough bit. That is a good few years down the line considering they are not even born yet. So need something in The mean time.Times were different then, regarding child seats, but my kids went in the back, sideways facing, with lap belts & booster seats as soon as they were big enough.
