I am posting on behalf of my mate who has an audi a3. Basically, we were both sat at the traffic lights, waiting for green. behind us on the right was a road leading to an industrial site. The lorry driver took the turn too wide and the back end hit my mates car. This caused the rear quarter to tear open etc. The lorry driver shot off while we got out of the car and shouting for him. We set off to track down the lorry and some helpful pedestrians and driver helped us track him down. We got the witnesses details etc. and the lorry driver when questioned put his hands up and said fair enough it was his fault. we got the detaisl, and because the guy was under business insurance we had to make do with the busienss insurance details. However, my mate has had his glass tinted the previous day and also he had also put on the S3 kit, and the insurance doesnt know, he was goint to tell them this afternoon. What the question really is, will my friend get penolised for him not declaring the mods, even if it is the third partys fault. I mean he's not bothered if they dont pay for the recovery of the mods, but he is just worried if the third parties insurance will say your car is modified we will not repair your car. Or has that got nothign to do with the third party. Will the the third party contact my friends insurance? and tell them about the mods? Thank You Input will be greatly appreciated, and please no comments about him not declarign the mods etc. as he was going to that very day.
