I've been debating on whether or not to get the cargo cover. I have seen positive and negative posts here. I'm trying to see what it looks like with the hatch closed. I've searched images all over the web and YouTube - but they all just show it open. I can't visualize it. Also, if you just want to put groceries in the back under the net...do you need to retract it, or just for large items? Thanks in advance for your help!
