Yeah i had similar damage to the car (same side) which was done by someone before and they owned up to it, the quotes i got then were between £1k - 1.2k to repair, i went for one in the middle and it was a great job you would never be able to tell.
I have not got the money at this time to repair it out of my own pocket this end of the year, even if i could repair it myself then there would be no chance of me getting the money back if the person who did this does get found...
Put it this way i would rather lose my excess of £150 and pay a little more on insurance then lose over £1000.
The insurance co said that my insurance should not go up to much due to the circumstances (no evidence that i was in the wrong bad as car was stationary no bad driver record etc, etc) and there is a "chance" they will be able to settle the claim with the other insurance company if the guy is found...
There should be a very good chance they have it on camera, there was one pointing directly at my car and the exit of the car park so either way they should defo get the reg number... even if he is not insured at least i know he will be prosecuted by the police and possible for it not to happen to someone else.
It’s a bit of a gamble but either way i do this i am probably going to be out of pocket but it just depends how much
