CONTINUED:
Caprice wagon 3rd seat foot well:
12v compressor
toolbox
there should be a small Craftsman ratchet set but it's not there
Also not pictured in the Caprice is a first aid kit, a tire gauge, many of those cards you get a funerals/wakes in the glove box (this car has been used for every funeral in my family), and a bell from when my cousin got married.
And now for the Mustang
lets start with the trunk:
toolbox
Craftsman ratchet set
many, many, many towels and rags (some of them are better than the one's in the house!

)
dust brush
12v compressor
12v vacuum
folding chair (American flag)
Rubbermaid container with cleaning supplies, flash light, and transmission fluid
roll of paper towels
card board box with assorted stuff (antifreeze, pens, paper, picture album, original paperwork for the car, original dealer brochure, maps, funnel, cheeze cloth)
The thing to the right under the plaid cover is the spare tire.
and the last pic is the Ford bear I got that's almost the same color as the car. He stays buckeled in the back seat.
