It's a matter of principal, not the money, it will only cost me £75 if I go through insurance.
I have dashcam footage of me parking the car on my drive with no crack, then starting the car up with the crack.
The crack starts where the windscreen joins the car below the wipers and below the line of the bonnet, and then branches out into the 2 cracks, so it's almost impossible anything could impact there. I do have a photo of the front, but due to reflections it's extremely hard to see.
I have an appointment with the dealer on Thursday, so let's see what they've got to say.
