Since it's on the crown (bend) of the panel and it's also on the end of the panel, It won't be easy to get out...but I do suggest using the best "Painless/Paintless Dent Removal" business in your area. I'm sure whatever they do will be a vast improvement...for only a couple hundred bucks.. It's totally worth it. I've seen them actually work miracles..
Well, At least the dent/ding wasn't on your classic mustang.... ;o)
