In order of f7cked-off-ness:
1 The dent
2 The fact she didn't even offer to pay even some of the repair
3 The sob story
4 The 'you have a new car so you can afford it' attitude
5 The fact she didn't get her child to even apologise
6 The fact she lets her 5 year old open the door unassisted

In fact, they all f7ck me off!
I'll be getting her to pay I think. Thanks all!
PS Yeah if I had got a VW approved quote then it would be at least double that - which I'll do if she quibbles this quote.
