Definately horrible, I would recommend to not go to your mercedes dealer as Dealerships all all on how many repairs they can get out of you. Try finding a responsible mechanic that knows wetsanding a collision repair.
Somehow that made me think of that thread by Joe from Superior Shine, what was he detailing, a McLaren or something, and he had the pic of him sitting in the rolling mockup with no body panels that he said was the only one he could afford...LOL
