We had a rock hit the windshield on a road trip back from Florida. The initial chip grew to several inches long and had to be replaced. State Farm was leery of Tesla prices and asked me to look at a (very good) local glass shop. Their cost was going to be 925. The Tesla shop quoted $907 plus tax. Having it done at Tesla next week. They are giving me a loaner. The shop would have done it at my home or work, but would have had to wait for parts.
