Cargo bin and side lining walls for automotive vehicle

A cargo bin assembly of an automotive vehicle includes a recess that extends below a floor surface. The recess preferably has a stepped conformation where a first, shallow rim portion receives support members without the potential for interfering with items stored in a second, deep storage portion of the recess. Preferably, the deep storage portion is dimensioned to receive side panel lids from side storage assemblies. Removal of the generally planar side panel lids allows elongated items to be received in the cargo area, and the cargo recess allows the side panel lids to be stored. No openings are provided along the lower portion of the side storage cavity to prevent collection of dirt or debris.
