In case I needed to move questionable materials.

Under cargo tray.
You remove the plastic tray. In AWD models, the plastic tray is much smaller.
Thereā€™s almost 12" of space under there to stash stuff. Same on the other side. You could fit aĀ premature born baby inĀ there, but I donā€™t recommend that.

Where are your car(s) ā€œsecretā€ compartments?
