Have a dent removal specialist do it, don’t bother with the insurance as they will send it to Nationwide and it will be ruined when it eventually comes back.
Like Fordmax said, it’s up to you if you get it done straight away or if you can live with it for the next 2+ years and get it done before it goes back, personally I always get stuff like that fixed as it bugs the hell out of me every time I see it.
