I'm looking at the '04 Accord for my next car and would like to know how "rear hip room" is calculated. I'd like to fit two pet carriers (which are basically rectangular boxes) in the back and would need a total of 52" lengthwise in the back seat. Rear hip room for the Accord is 53.5" but I am wondering if arm rests or anything else protrude into the space and are not accounted for in the stated measurement. The obvious solution would be to take the carriers to the dealership and see if they fit, but I don't want to sit thru the sales pitch again ;-) TIA for any responses ... Sara
