methinks you may need a baby enthusiast forum (lol) more so than a car enthusiast forum. either way, this might prove to be more useful

in my experience with car seats, i can't imagine a murano securing 3 across the rear seats. i've seen 2 baby seats in an xterra, and there wasn't much room left in the middle for much else than a few toys to keep the babies occupied.

this wouldn't matter.
*edit- upon clicking a few of those links in the google search, it seems it's more of a problem with the car seats being too wide than the seat space available. i guess everyone i know with childrens prefers the escalades of carseats over the civics.
