On my way into work today I heard that dreaded "tink" on my windshield and sure enough there was a nickel size spider web just wanting to grow. By time I got in this morning the chip grew into a 7 inch crack. Not only that a Arlington County Officer pulled me over and gave me a safety warning to have it fixed in 14 days. With the heat the crack is sure to grow. The question I have is should i have any glass company replace my windshield or should i go through one of the local dealers. I have a 01 530i with the autosensing wipes.

Any thoughts?
