As others have said:
Arm rest for sure.
This is the one I have and prefer, and it's been great.
I'd also add the J
etta trunk hook. I bought two of them and used a couple of self-tapping screws to attach them up underneath the package shelf in the back. Super handy for keeping your grocery bags from sliding all over the place, and the fold neatly out of sight when not in use.
