Bit late to the party (sorry to see the damage... bummer).
Surprised that the paintless dent repair folks said that they could not do anything. As I had a similar dent on the crease line of my front wheel arch of my new Focus ST (front wheel arch though). And though they said it might be difficult to do, they simply removed the wheel / arch liner and worked their magic. And I'll be damned if I can see where it was now. OK... if it's 100% clean and looking at the wheel arch at exactly the right angle in strong sunlight... you can see a slight dimple effect. But if you did not know, you would just think it was a trick of the light. Though I suppose every car is different.
