WOW!
Good to hear you are not seriously hurt though, although need time to recover.
The car looks really bad, and since I have the same car/colour, but 5 door, its a reminder for me to drive calm. Then again, the worst thing about all this is, it wasnt even your fault. It was all because of some careless idiot not watching the road in front of him.
Dont let him get away with it. Chase it as much as you can. I mean, whats the worst that can happen now??
Best of luck.
On a sidenote - can you also not claim for your injury??
Im sure you can, as my ss in law was hit from behind once, and put a claim foward and she was awarded over £1k for her ack inhury - similar to yours.
Try one of the accident claim companies you see on TV - a no win no fee thingy - Im sure you'll get some extra for your injury. Worth a shot aint it?
