When I bought my 2010 Fusion used, it had door dings and little dents all over it. Some of the dings/dents had paint transfer, some had scratches in the paint, and some of them had very noticeable chips in the paint.
I did lots of digging, calling around, etc.. and found myself a very good Paintless Dent Removal (PDR) guy. Luckily, my guy charged me only $300 to do the entire car, although he forewarned me that some of the dings and dents were along body lines, and so he couldn't promise he'd be able to get them all out. Turns out, he's VERY good, and he did... but I digress.
The first thing you need to do is find yourself a good PDR guy. Check with your local car dealerships, etc.. They most likely will have found someone who does good work and doesn't charge too much.
You'd be amazed at what a really good PDR guy can do.
Once you've had him fix your dent so it's gone, then you'll want to do like others have suggested, and find out what exactly has been done to the paint. If you're lucky, it's just paint transfer, and a simple polish should remove it. Otherwise, if it's deeper, then you can go from there and either correct it with some compound, or fill it in with Dr. Colorchip or some touchup, etc..
