I had a big rock hit the windshield on my G35 a few years ago. I called my insurance company and they said, sure, we'll get someone right out and replace it in the parking lot where you work. Great service ! Or so I thought. The instant I got in the car to drive home I thought I was loaded. The glass was not the same quality and in fact was a bit wavy around the curved edges. Passengers noticed it also. I don't remember who did the install or who the glass was made by, but I would not again allow them to replace the glass with other than OEM.

That was why I went to a dealership. To make sure I got Nissan glass... But, it's not like I made out much better either. Looks like a high schooler did the work. After driving her I feel like there's wind noise that wasn't there before. But, I have no way of really checking that...
