Got a question for those who have this option. Do you think there is sufficient room to carry four good sized adults and have enough room for two small kids in thier cars seats in the third row? By full sized adult I mean six footers.

Any input welcome as I am considering a RAV4 purchase.

We just bought an 06 RAV-4 base last week. We did not get the optional third seat. However, when we were at the Auto Show in the spring the model they had there had that option. From what I can remember it is more for an emergency type use. If you want to carry 6 ft. adults in a third seat you are better off in a minivan or full sized SUV. I really don't even think a Highlander there was much room for the third seat. Your best bet is to simply goto a dealership and see for yourself I suppose though.
