I don't mean change cars every few months - Im talking about changing cars every day. In the space of one week I had to change the seat into 4 different cars.... has anyone else had to do this? That would be $120 plus the fact you have to book it in each time. I know it is my child safety but once you know how to do it - I can't see why you have to have it fitted? Any advice thanks because we still change from a few cars regularly - especially now that I am back at work.
