A while back I emailed Mercedes-Benz of Ft. Mitchell Ky and Mercedes-Benz of Cincinnati and asked them the same question. "If I have a serious problem with my Chrysler Crossfire would your service department be able and willing to work on the car?". Mercedes of Cincinnati responded the next day and said "We would gladly service your car at the same shop and parts rates as their MB products. Mercedes-Benz of Ft. Mitchell did not respond to my email.
