Yep. I'm the same way. I recently swapped cars with my wife so I could work on some accumulated minor problems with hers. I was surprised to see just how much useful stuff I'd stuffed into various nooks and crannies, beyond the usual Get Home/Bugout bag, first aid kit and tool kit.

Yeah, cleaning out my car is like Christmas. You never know what you will find in there. But it is all useful!

That was Stu's car after all the fast food bags and wrappings were cleaned out.

That's exactly what I have discovered just recently - a whole lot of great stuff I have tucked over the years in my spare tire well and in hidden compartments around it in my Forester!
