Went and had another look at the '09 Odyssey to try to convince myself to buy (my wife wants this car for 7 seat option). I compared it to the previous model, the dealership had a used model on the floor as well.
I think the middle row seat in the previous model for seating 3 people in comfort was better. The old model was a flatter bench like structure with a 60:40 split. I think the older model was more user friendly in seating 5 using the 1st and 2nd rows only.
New model is similar but has a V like shape and the middle seat in the middle is very skinny, and hard. It folds down to be drink holder for the larger bucket shaped comfortable seats next to it. I hope I have described this sufficiently, if not think of the Toyota Kluger which has similar 2nd row. I think this middle seat is one that people will only use as a last resort, and only for a small child.
With the anchor points in the roof for the middle row (in the face of people sitting in the 3rd row), and in the way of storage space for the third row, I wonder whether in Japan they use a different anchoring system for child seats, because as a designer of the vehicle there are better places to put the anchors so they are not in the way (that is, on the back of the seats under the head rest).
I also wonder whether this car has been designed for people in Australia to use with child seats? Are the anchor points a compromise to fit Australian safety standards?
My discussion with a salesman at one of the many dealerships I have visited to see this car, went along the lines of - in Japan this is designed to carry 4 people with option for additional 2 in the back if you go on short outing .....
I think the car is a great vehicle, but not one for people with young kids requiring the use of the anchor points, unless you are willing to compromise with above shortcomings. But why should have to compromise?
