I have just purchased a A3 (8P) Sportback after having a A4 B6 for 2 1/2 years. My 8P has standard fit ISOFIX in the rear, unlike my 2002 A4.
In its place my A4, Golf mark 4's and I am hoping 8L A3's had a great rear seatbelt feature, it allowed you to pull the seat belts in the rear fully out and then they would ratched back in locking any item (in my case a child seat) in place until the seatbelt was undone and fully retracted. I am guessing Audi droped this once they started fitting ISOFIX.
Has anyone used this in a 5door A3? can some one check for me that it has this feature? If 8L's have this is there any differenace between the rear of an 8L and 8P as i really want to get a set of these belts.
