Also make sure if repaired your car is'nt cat C or D recorded as this will retract the car's value should you sell in the future.
Best of luck, Guy. 
Unless the insurance company will offer you a 'cash' settlement and not record the accident, the car will either be a Cat C or D.
I had someone drive into my Galaxy before I sold it and although it had minor damage there was enough to write it off. The guy I dealt with from the other insurance company seemed reluctant to write it off and actually come and inspect the vehicle himself and offered me a cheque almost to the value that I paid for the car in the first place and to not record the accident. I was happy he was happy so sometimes you can deal with these people for the better, I guess it just dependes on circumstances at the time.
The problem with repairing a recorded Cat C or D is some insurance compainies wont insure you, some will only do it once the car has been VIC checked and then, should you have an accident again some companies will argue about the value of a write off. Can be a little troublesome.
