I've been pushing my insurance company the last few days and have come up with a bit of a result.
The Golf will no longer be written off, I'm guessing the cars condition, mileage and mods were better in the pictures than the engineers were expecting and they couldn't just class it as a £500 book price sh!tter like they wanted to.
So they have offered me £680 for repairs which I am going to refuse. It's in need of paint on the bonnet, offside wing and bumper and also the nearside wing blending in and I have been getting quotes of around £800 for this so I'll be requesting an amount close to this.
The police have also been in contact; they have been round to the registered keeper of the camper but he is away working (according to his mother) and doesn't own the van any more (even though it was parked outside the property, go figure).
She has been given a form to pass onto her son which requests the identity of the driver at the time of the incident to be named within 14 days or he will face prosecution. Sounds very similar to a speeding offence NIP
So a result in both aspects
Interestingly I have looked back on the campers old MOTs via the government website and it appears to have had a rust problem on the nearside for quote some time...
