My stationary vehicle hit by 3rd party

[dubway]

Basically my parked car been hit by a other party (fully comp)
I have his details etc witness etc and I'm covered 3rd party only
Long and short of it , my cars 1995 so will be written off
Needs boot lid and a lamp bumper painted job done
I'm in no mood to loose the car for that and have the parts allready in stock in different colour
Company need s two quotes which I am in process of forwarding to them
But at 700£ plus parts at mfr cost you can see where I'm coming from guys
Was looking to go CIL and repair car my self any ideas or thoughts .....
Cheers
