It turns out that Hastings also use Nationwide Motorglass as their second preferred supplier. Explained the situation and they put me through directly to them instead. Have got an appointment booked Tuesday - AutoWindscreens next appointment was a week later :/
Explicitly mentioned the special window moulding to them as well and asked them to ensure all the correct parts would be available.
And you were right, did a bit of searching around, £500 seems about right for my screen.
Finally got the new windscreen fitted today. It was due to be Tuesday, but there was still a little bit of faffing. I decided to email the girl dealing with my enquiry asking her just to make sure that the technicians were aware that my car required a bespoke trim for the Tuesday booking.
On Monday she phoned me and told me that she'd spoken to the technician who was aware of the issue and told her that ideally both the glass and the seal need to come direct from Toyota, and she'd need to authorise that with Hastings before proceeding, providing I'm OK with waiting a couple of days to get OEM glass? Yes, of course I'm fine with that
Tuesday, she phones me again, authorisation secured, glass/seal ordered from Toyota, appointment re-booked for today, Thursday, between 8AM-5PM.
This morning she gave me a courtesy call to inform me the technician was due between 12-2PM.
At just gone midday, the technician phones me and turns up within the hour, right in the middle of the ETA.
Polite, friendly, knew about the issue with the OEM seal (he'd done a GT86 before). Took him and his assistant no more than 20 minutes to replace the glass without any signs of damage, all trim and scuttles properly reattached. Drove the car home a few hours later in heavy rain and no signs of leaking or anything like that.
So, from gross incompetence to having the issue dealt with within a week by someone with experience and using a proper OEM screen, and all the while kept informed by the same contact in the office who was friendly and went the extra mile to make sure I was happy.
tl;dr - New windscreen.
Auto Windscreens = crap.
Nationwide Motorglass = excellent
