Although many of the newer Mercedes vehicles come with Pilkington glass, there must be a different grade that the outside glass companies use.

My 97 E320 got nailed by a rock and had to have the windshield replaced. I asked for "premium" glass and got Pilkington. Immediately, I noticed that the glass information is in the lower passenger corner where the factory sticker goes. The fit was horrible. The outside bottom trim piece no longer sat on the glass and the inside pillars didn't line up with the black frosting around the windsheild. To make things worst, there was a wind buffering sound at freeway speeds.

After complaining, the windshield company replaced my Pilkington glass with PPG. All the problems went away.
