^I agree. Its got a dish to it and all, that should be easy to pull out and straighten. Once you get the dish pulled out on it, take a stud gun and use a dent puller on that crease. Imagine how it fell onto the fender and reverse the process when fixing it. Sheet metal has a memory and wants to go back to its original shape. Beat on her easy with a hammer and dolly and finish with some filler.
You should be good to go! Take a straight edge to the fender like a ruler off of a square and you can get it unbelievable flat untl you get into the contours..
