My folks had my car down in Florida for a few weeks, and it came back like this.. My best guess is that when my Dad used a squeegee to clean off all the bug crap at some gas station, there must have been some junk caught in the sponge that scratched the heck out of the windshield. I showed it to him today, and he played dumb.
A new windshield is out of the question, as a replacement is VERY expensive for this car, especially since the radio antennae is built-in. I thought I heard that some of these could be buffed out somehow, but didn't know the details on it and was hoping someone here had some experience in this department.
