My 1998 E300's windshield was hit by a rock on the way home from work yesterday. The result was a dime sized crack at the two o'clock position while sitting in the drivers seat. I called my insurance company and setup to have the windshield repaired. Fella came out and attempted the repair. When completed, the crack was still very noticable. I have had other windshields repaired and once completed, I could hardly tell. This is not the case on this vehicle. I called the insurance company back and explained. They said so ahead and have the windshield replaced. This leaves me with two questions.

1. Should I have it replaced or live with the blemish ?

2. If the answer is to replace, I notice the windshield has a Mercedes logo in the lower left corner. Should I specify a Mercedes replacement, or is all glass created equally?
