What car seats do you have? You will need at least 3 Teathers for carseats. Tethers are the ones that go behind the seat and help reduce head movement in an accident. LATCH are the lower anchors in the vehicle seat. Once your children hit 40lbs, you need to use the Seatbelt and Tether to install the carseats. All Honda's have 40lb LATCH limit, the dealerships have no clue about LATCH or Tethers. When we went car shopping they had no clue what a Tether was. I did have 06 Pilot and loved it. But getting to the 3rd row with 3car seats was not always fun. I had 2 Graco Nautilus in the 3rd row. One on the driver side, the other on the Passenger side. I also had a Rearfacing Britax wizard in the middle row passenger side. It was easier to get to the 3rd row with the wizard passenger side on the 40 split bench then it was to have it on the 60split bench. I have also had Graco Safeseat Passenger side middle row. The passenger had no leg room with the Safeseat there.
I have also had all in the middle row...RearFacing wizard passenger LATCH install, Graco Nautilus middle seatbelt tether install, and Graco Nautilus driver side seatbelt tether install. All were indepdently tight with less then 1in of movement at the belt path. I do know in the 09 Pilot it has 3 sets of LATCH and 6 Tethers. LATCH is driver and passenger side in the middle row, and in the third row its passenger side.
The best thing to do is try the car seats in the car befor you buy the car. I now drive a 09 Odyssey and I am loving the mini van life. Much easier to get to the third row and very very roomy.
