I'll start. The issue I mentioned above is a scuff in the paint. I'm positive that a previous owner walked up one day and found a speck of dirt or tar or bird poo or something on the paint. Wanting to remove it, he grabbed a tissue, napkin or paper towel and started scrubbing. I did the same thing one time when I was new to vehicle care and always regretted it.

Tip: NEVER use anything made of paper on your paint. The result is similar to using sandpaper. Here is one of the 5 scuffs in my paint that I would have to risk burning off my clearcoat to remove (it's the light horizontal & vertical scratches in the dark section of the photo, not the squiggly reflection thing going down to the bottom-left corner):
