I'll take the car to one of Just Car's preferred repairers this week and get a quote.
After I find out how much higher it is than my excess, then I'll decide whether to make an insurance claim.
The problem is that I don't easily trust anyone to work on my car haha, unless it's a job that I wouldn't be willing to do myself (in this case I could do it myself, apart from the painting).
I'd prefer for the insurance to just pay for the parts, but of course there are liability issues if the repairer doesn't install the parts themselves.
