Hi everybody I'm after some help. I am looking at buying a Y reg 2.3 zetec but it doesn't have isofix. After scouting around for an answer it seems that the sharan and alhambra had isofix installed on their seats but the galaxy didn't. Am I right in thinking that the seats are interchangeable between the 3 so if I find a sharan or alhambra seat with isofix I can just swop it for the galaxy seat? Any clarification/help/advice would be much appreciated, thanks.
