Just an update it looks like i will be trying to get her to cover the cost now, there has been some leyway, but still not great she is very slow at engaging.
I did the rounds at the local smash repairs nobody is willing to give an exact quote as the damage is quite extensive, could be classed as a write off. Luckily i have somebody that works for a solicitors office that deals with these types of situations which has been a great help.
She did give a lowball offer to get this done and dusted unfortunately it wont pay for half of the vehicle of the same make and model, hoping that it stays out of court so i dont have to get nasty and stray from my passive self.
Thanks again all for the confidence i wasnt in the wrong
