I will disagree on this one. One of the Vietnamese colleague of mine (who claims to be GM fan but humps Toy) just ordered 2 4-cylinder RAV4 to send to Hanoi (reason, cheaper taxes on imported goods)
He contacted all the dealers in Central FL area. One of the dealer's email read this, "Although Toyota provides this option, this version of the vehicle is build to order. The waiting time for it is anywhere between 4 to 6 months. The nearest car we found was in one in Idaho on the dealer's inventory list and there are not many vehicles available in the United States."
Further the dealer said that my colleague had to pay full price on them, (since they are not on the lot, hence forget haggle). My colleague confirmed this and the availability verbally with another dealer.
So I KNOW for a fact that the so called 3rd row option is only a GIMMICK, NOT a fairly high take rate at least for the RAV4.
