My wife and I are expecting twins in Oct. We have been searching for car seats in area stores. When reading the owners manual I came across info on Isofix fastners. I know that the U.S. is slow to put out the Isofix car seats probaly not until the year 2002. I was wondering if anybody knows about the Volvo isofix car seats if availble or any company that makes the isofix car seat?
