A friend has offered us her Maxi Cosi Pebble as her daughter has grown out of it. So I went to the Maxi Cosi website and put in details of our car (2002 Honda Jazz) to see if it would fit, and it said that we couldn't use Isofix, just the 3-way seatbelt. But I know we have Isofix in our car, because we checked. Are there different kinds of Isofix or something?
