Am I understanding correctly that the shape of the shell is the same? The old Frontier would not install in an 07 (or similar year) Subaru Forester. When I tried it quickly at BRU, it seemed that the strange geometry of it with the recline block forward made the angle so severe that it would not fit into the seat well, but I am not that experienced. Someone more experienced on here (cannot remember who right now) said that even when she really worked at it and managed to get it installed, it was really hard and still was not what she considered to be a good install. I do not recall if she said why, the belt path or if I was right about the shape of it not fitting. So basically, the old Frontier does not work in the mid decade Subaru Foresters (not sure about other years) and where I live, this is a very popular vehicle. Assuming the reason is the shape of it, it sounds like the new one won't change that, right? Although I may have to wait until someone with a Subaru Forester tries it and reports back to know for sure. Last month we bought a GN and we are very happy with it. However, if we were to buy her a second seat, I would like to get the one with the highest harness since she is very tall. Thanks!
