The only way I can get my luggage cover back in, is to drop it in from the top, with the seats folded down. The seats will now fold up, albeit with a small gap between seat backs and luggage cover. Why then is there a matching groove to attach it to the folded seat backs, like in the s204? In the s205, if i attach the cover to the seat backs, the seats won't fold back up as the cover can't meet the 2 drop in points. Are these attachment grooves ONLY there to secure the cover if it has been removed from the luggage covering position? Am I going mad?
