I carry around shelled and unshelled peanuts in my Micra. This morning, I found that the bags have been eaten through and someone ate dinner in my trunk area. What I need to know is if it is normal to have an opening on the left side rear near the bottom if you are looking into the car. It is a perfect circle about 3 (?) inches across and I have never noticed it before... through the metal and the carpeting there. I wonder if it was covered and if I can keep the towel I stuffed into it there or should it be "open" for some reason. Any help much appreciated.
