Try Dent Wizard or Pres-a-dent
My P5 had a golfball sized dent above the driver's door below the roofrack that I didn't notice when I bought the car. I got home, then noticed it in the garage when the light hit it just right. Called my dealer the next day, and they said no problem, Dent Wizard does this kind of work for them all the time, and got them in touch with me. Took the guy who did it about 2 hours, but you would never know there was a dent there in the 1st place. Dealer paid the cost. This dealer also sells Mercedes, Audi, and Porsche, so anyone they use must be good, and this guy who fixed my P5 was.
A buddy of mine had 3 dings removed from his Accord coupe at Pres-A-Dent, and it also looks perfect. Cost him about $100.
Key to both repairs was that the paint wasn't damaged. If it hasn't been, they can fix that dent.
