Can anyone clarify what ISOFIX is? We currently have a car with ISOFIX, but are thinking of buying a car that doesnÂ´t. And the Mrs is a bit worried on this matter (no kids currently around by the way). I was under the impression ISOFIX is a quicker way of swapping car seats around from car to car. We only have one car, and will continue to do so,so are there any other points about ISOFIX that would make them better than seatbelts for nippers in car seats? Cheer for any assistance.
