I use two of the small plastic totes that fold up when not in use. One has my emergency kit, tool box, fire extinguisher and small blanket. The other has reusable grocery bags. Both are simple to remove and sit up against the back seat. I also turned the mat over and installed a trunk tray from my old 325i wagon. In the past I've also used worn out rubber mats to protect the trunk and prevent sliding.

 

Well let's see...
I have a small shop vacuum (for computer cleaning), my computer tools, car detailing accessories (for unexpected bird doo doo and window glare), a compact tire pump, and a few other miscellaneous items.

 

Lol good idea, I hate it when that happens

 

that's a lot of things you have there...now I feel like my trunk is too empty. I only have a bottle of Meg. quick detailer and a microfiber for bird's doo doo, and a bottle of oil just in case when that damn low oil level shows up

Need to put more stuff in my trunk now just in case I might need while on the road

 

I honestly feel birds tend to target real shiny cars, seriously. I never park in the flight line of a tree(s) either because that's just asking for it. I think maybe the shine blinds the shit out of birds, literally.

 

got a 3 section cargo net from target that expands and retracts from Target.

 

"You guys are cracking me up. How much crap you hauling around?"

I was thinking the same thing...
