So, after 10 days and 684 miles I got my second windshield chip today. Unsure if these windshields are just particularly fragile, or I'm just very unlucky.
The second chip was a "spider fracture", which got dramatically worse when repaired.
I *then* discovered that a new windshield? **$3200** including labor, and will require vehicle coding when replaced (and there goes my custom coding!).
So.... make sure you've got decent glass coverage!
