Maybe those people need to buy an IS200, once the seats in its near impossible to get it back out, it ain't going nowhere, its a pain.
I also have one of those base units that fit in stay in position, which you then clip the child seat into. Nice and easy, only problem is that the scooped rear seats make the angle far to great and the babies head flops right forward in a rear facing seat.
Guess I'm gonna have to get a Volvo or mondeo
