UPDATE:
Turned up at RAC/Auto Windscreens at 1pm. Man let me inspect the new screen. Genuine Toyota and he said that he'd have been surprised if it hadn't been. He looked over the car, checking off points of damage etc and I watched him drive the car into the workshop.
Went for a walk and, about 2 and a 1/2 hours later, it was done. Car was parked in exact same spot. Which is always nice.
The screen 'looks' lovely. I say 'looks' because it's so pristine it's actually hard to see the glass. I was so pleased I even purchased some lovely new wipers to go with it. Seal looks a tad different but better than the old one.
"Any negatives, Martin?"
Yes, actually.
Big Macs don't taste as good as I remember.
Goodbye.....
