More battle damage and a nasty scare

[Gaz85]

So last tuesday (12/08/2014) an old fella decided to drive into the side of my car after exchanging names and vehicle info i got onto my insurance company (tesco) to get thing's moving well after giving them the reg number of his car and the company he said he was with they couldn't find him on the insurance database at that point i crapped it because i don't have protected ncd yet, anyway i got in touch with the guy and he then gave me the right details it turned out that he was with admiral but funny thing was when i gave them the reg of his car they said that it wasn't the right one for the car even though i told them that i had taken a picture of his number plate whilst taking pictures of the damage to both my car and his anyway my car was deemed a total loss and only valued at £700 if they took the car which after the money i have spent on it wasn't an option so they then said if i keep the car they could only give me £560 which i ended up taking so now i'm trying to decide what to do. here are the pictures from the damage.......->
