Iím pretty sure you can get an 8 passenger Limited. You lose the tri-pane panoramic sunroof unfortunately, but itís like that throughout the model line up. I also donít think itís technically a bench seat. More like 3 separate seats that sorta make a bench, but either way it seats three people and they are removable and what not.
As far as the leather goes yes I believe the Limited has higher quality nappa leather. As far as differences in the seat besides that Iím not sure, but they do look a little different from what I have seen. If anything the Limited seats might be a little more firm since they are also ventilated/cooled. Overall they are nice seats and I enjoy them. We purchase our 2017 Limited used last month and we really like it. Paid 36k with only 4300 miles and it is a loaded up Limited with a 50k original msrp.
