I bought my 300 used and there seems to be scratches in the windshield on the outside passenger side. It looks like someone took a course material and rubbed it on the glass. When I check the outside of the glass closely, it looks and feels like there is a plastic film on the surface of the outside. Is that how everybody's windshield is? With this soft "film" on the glass, every little rock etc that hits it leaves a mark. Has anyone else had this problem? Are there various different qualities of glass that would make a replacement worth while? If this was a piece of electronics I would think it was a plastic film from the factory that needs to be peeled off!
