Here is a diagram of what the R1S' child seat latch system looks like.
Welcome to the forum! There's some discussion on those mounts here:Hi Miles,
My heart goes with R1T, brain with R1S.
I would love to have two extra seats and large luggage space, but on the other hand, having a pickup and adventure tent over the bed? damn, I love that idea.
And I really love to travel with my kid on the front seat as we have a chance to talk, headbang to the music and you know.. everything. but I just cant accept anything less than Isofix mounted seat.
I dream they could introduce matrix lights that I love in my current car, but I guess that would be much much harder, because of the shape of signature lights.
