I know that it is tempting to find low cost used car seats. They grow out of them so fast and I have twins! HOWEVER I need to caution you that when you buy a used car seat you don't know if that carseat has been in an accident. Once a car seat has been in an accident you are supposed to destroy the car seat (I work for a police department so I am up on these thing.) If you are going to go forward and use this seat just contact Peg and they will sell you the missing pieces.
