Under climate controls:
Lighter, matches, toothpicks, nail clippers, individual wipes for windshield wipers, floss
"secret" glove box:
GPS and cord, radar detector, sometimes point and shoot camera
Rear right cargo area (no subwoofer):
First Aid Kit (it's come in handy), small container of ear plugs, flat nylon strapping, workgloves x 2, Nitrile gloves, space blanket, sometimes flares, glow sticks, Camp Currency (toilet paper!- don't laugh, everyone who has laughed at that has had to use it the next time we went out in the wild...)
Left Rear cargo area:
Some rope, and my front license plate (when I go to the bay sometimes I put it on to avoid the citation. Yes, it's happened to me)
I also keep a bag in the back cargo area with more road stuff like flares, scrapers, other items I need for the car, the dog, or the trip...
