>>1788751not a c40 but sounds like same principle in my outback. The rear seats fold down and make a long platform that slopes downward towards the back of the car. Not very /comfy/ to sleep on. I made a plywood frame to make the platform flat when i'm sleeping on it, or slides together so i still get all of my cargo space minus like 4 vertical inches and can still put the rear seats up. the sliding portion covers up the rear seat footwell and also turns into a table that you can kinda see in
>>1779320anyway hope this helps. the space under the platform is convenient for storing jumper cables, recovery gear, and shit you don't want passerby to see
