I just had my windshield replaced on Friday by a Glass America installer. He was nice and did a fair job, and I asked for either Pilkington or PPG based on Nasioc comments and elsewhere. However, PPG Auto Glass is now PGW, which is what I got, and the piece is TERRIBLE! Very wavy and distorted in several areas. When driving, the white line on the side of the road looks like a zig-zag.
I'm calling Glass America Monday to see what I can do. They were right around the same price as Safelite, but unlike Safelite, GA agreed to use Pilkington or PPG glass. Cost was $240 (out of pocket discounted price), although in three different phone calls to them I never got the same price twice...
