If so, can you tell me if there is a place to attach an upper strap for a child seat, and if so, exactly where is it? The US owner's manual for my 300E says the car has one but I don't see it, and I suspect that US 124s lack this feature. I have seen this issue discussed on the board before, but have never seen a definitive answer.
