do mercedes take special windshields? 500E?

[hedpe]

Ok, so my cousin bangs on my windshield to kill a hornet and completely cracks the windshield sending out about foot long spider cracks. Called the mercedes dealership, they said that they need to put the windshield in and get a special windshield.
Are they just trying to make a buck or two, or do mercedes really take special windshields? It's for my 500E. Because if they do take special windshields my car is out of commision for 4 days until they can do it, if not i can just take it to a regular windshield place today. Let me know, thanks guys.
