Hit and run on my X5 need help

[np2004]

Last night as I was grocery shopping at a local market a witness told me a large SUV with an intoxicated driver hit a vehicle in the parking lot and in trying to flee hit my 08 4.8i with the side of his SUV. The witness could not see the license plate since it happened so fast but gave as much information as he could to the police officer that arrived. I filed a police report, spoke to my insurance company, and tried to see if the grocery store had cameras which they didn't in the area my X5 was. The damage done was the back tailgate is smashed in the portion that comes down not the trunk portion that can be lifted up and the bumper has some deep scratches which were all noted on the police report. I am taking my X5 to the dealership where I purchased it from for an estimate on how much it will be to replace the damaged tailgate and bumper. When I am there should I have them looking into anything else in particular that could have been damaged internally to the vehicle since it was parked that I cannot see visually? Thanks
