Do earlier series Mercedes S-class sedans have factory bulletproof glass?

Question:
Ok why I ask this is because whenever I see a previous model S-Class sedan (early '90s-early '00s type) and the windows are rolled down it looks like the glass is 3/4-1" thick judging from how wide the frame is on the inside edges of the doors. The only practical purpose for super thick glass I would imagine would be for bulletproofing, yet this seems to be the same across all S-class sedans I see. Anyone know about this and if it is so, what's up with the thick glass if its not for bulletproofing? Lower NVH perhaps?

Answers:

When and why did Audi stop making the A2?

It's actually two panes of glass separated by a vacuum(sound does not traverse a vacuum), hence less noise is transferred inside to the driver.
