Doctor of Credit is noting that AMEX and Mercedes are cutting ties come Jan 2019. Noted in the fine print when signing up for either card is
Please note that the American Express and Mercedes Benz Card program will end in January 2019. Applicants can continue to apply for the Platinum Card from American Express exclusively for Mercedes-Benz, but, if approved, the Card will be replaced with a different American Express Card at the time when the Card program ends.

I never had any of these cards, but this kills the Mercedes Platinum card as a "unique product" to the Platinum lineup.
