Steve S. --
Here is an idea on dent repair which has worked well for folks in my unit with a similar dent:
There is apparently a "suction cup" type of tool (industrial grade body repair) that has been used to pull dents out. I have seen a few before and afters and it did amazingly well, and seemed to get 90-95% out on a low rear corner ding. You might give this a try.
