I've got some ideas, one of which I'm working on right now. My dad ordered this (link below) torque wrench and case a while ago for his G8, lost the case (eventually found it), and ordered a new one. With the new one, he drilled a couple holes in it and mounted it in the trunk of the G8. After the wreck, he took out the case. I have recently decided to mount the case to the cargo shade in the Aveo (I could've stowed it in the spare tire well, but the case itself won't fit down there). All I need now is a couple decently long screws and a couple nuts to act as spacers to allow easier access to the case's latches.

And when the weather gets a little nicer, I wanted to paint the silver interior trim pieces satin black. My dad had this paint that he was going to use on a Camaro part (didn't turn out right), and has a lot of it left over. I want to use a brush, as I think it'd look cool brushed.
