the compartment that's on the passenger-side of wagon, by the wheel. I don't use mine and rarely open it mainly because it's a hassle to just remove and replace the cover, and I don't know what to put inside! the interior is oddly shaped for me to fit anything valuable inside, like a laptop. and the lid is too cumbersome to really use it on a consistent basis. I have thought about putting in an empty emergency gas can (plastic rectangular one), but the space was too awkward to fit the can in without it moving about. so what do any of you brick nuts use it for? and what do you guys put inside? I need some ideas because it would be nice to have some use for this secret compartment. I feel only we volvo owners know about this secret space.
