I thought I'd update this to let people know how it went. I took the car into the Rockville, MD SC this morning for a 10:15AM appointment to replace the rear bumper and passenger side wheel as they were both damaged upon delivery. I arrived a little early, at 10:00AM or so and they took the car in, no problem. I was out the door at about 11:20 with a brand new bumper installed, brand new wheel, and they also took care of an issue with the trim for me as well without argument. They're busy over there but they took care of the issue quickly and politely. They made it right.
