DONT TRUST THEM
I have seen 2 friends burnt with guys that said exactly that, or "Mate I know a panel beater that will do it cheap"
F*** that, call your insurance company and tell them what happened...
why do you pay all that money??? they are there to help you. They will make money out of this guy, so they will be glad to help you.
Twice I got hit, and both times called them immediately. After explaining situation, they told me to go fix my car, and they chased the other guys for money.
there is a 99.9% chance this guy wll turn around after 2 months of chasing him and say - what are you talking about mate??? I never hit you!!!
Then you will be left with the bill.
Of course that is the worst case scenario, but it is very likely, and as i said, i have seen it happen twice!
