I've been waiting around a month for Autoglass to get a replacement windscreen in for my Model 3, no luck yet. Got a text yesterday saying that "due to a national shortage of Tesla Glass" they would not be able to book me an appointment, and that they would be in touch soon.
I've got a separate booking at the Winchester SC to replace the windscreen on June 7th, hoping Autoglass can come through for me before then though as I'd rather pay just the insurance excess than the full£700 + VAT..! I may have no choice but to fork out the money as my Model 3 makes up the vast majority of my deposit for the new MYLR being delivered at the end of June.
