Basically, if the repair cost is less than the deductible, its worthless. If its close to it, use your best judgement. If its significantly higher, hop on the that train. I have been down all 3 roads a LOT in the past, let alone having been a tech in a body shop for many years and butting heads with insurance companies, heh.
As for reporting any stolen items from the vehicle, not all insurance companies will honor that. Mine will, IF I have receipts from the purchase of the items claimed.
I am pretty sure MD doesnt dictate windshield coverage to insurance companies, but I could be mistaken. It was covered under mt insurance as Road Hazard. The $0 was acually a surprise to me. I was fully expecting to pay something.
