Car confirmed total loss

I have a golf mk7 R-Line, got a smack on the front passenger quarter. Damage doesn't look too bad, copart wanted to take my car via AA I said no. So agreed desktop assessment which I have just had confirmed is a total loss. They wouldn't give me valuation until they have had confirmation from AA. I really don't want to be pissing about going and forwards but I have had a independent valuation with Percayso of £13,510

My plan was to buy the car back as I have been quoted £2800 for the repair.

What do you think I should be expecting and should I accept nothing. Less than the valuation?
