Found a 72 Nova hatchback in a barn shed in northern Mississippi a few years ago. Cleaned it out real good. Got all the nests out of it and she looked really good for a 40 year old car. Got her road ready, pulled out the driveway and took the left and punched it. Right around 45 I started getting pelted with giant pieces of rat nesting and debris from the vents. Missed a spot
From my experience it is so the mice and other critters can more easily tear apart the interior for nesting.
