I think the bungee cords that hold the back seats up when folded forward are a poor design. Way to much effort required to hook them around the headrest  chrome tubes. I find it difficult and my wife finds it impossible. Look at the pictures and see the easy modification. I had some chrome 100 mm S hooks laying around in the garage,  I think they were only a pound for 3 from a market stall. 3 small strong magnets secure them under the seats when not in use so easily to get at
