Well, you do need to file a police report, especially if you plan to file on your insurance. Our deductible is $1000 as well and I would be inclined to repair it out of pocket.
That said... we drive Mercedes, 3 in our family. Do you know your dealer well? We met a guy, through our dealer who works on the side and does EXCELLENT work on high end cars. His work is impeccable and a fraction of the cost of the dealership.
We used him when hubby hit the garage door by accident. His bumper would have been $2000 on his E350 and the repair was $400. The garage door repair (total replacement) was $1000!! Daughter had a slight scratch on her CLK and he fixed it for less than $200. Same for me, I drive the SL550 and hubby, NOT ME, turned too close to a curb without realizing how low my car sits and messed up the bumper. The repair guy came to my house and repaired it for less than $400.
Find one of these special guys!
