Not sure what this means..Fiat changing platform on products

Sorry but the 200 is Manufactured and assembled in Sterling Heights Michigan. Doesn't get any more American than that!
Was! Chrysler 200 production ended Friday, Dec. 2, 2016 at Fiat Chrysler's Sterling Heights Assembly Plant, according to The Detroit News, Dec 6, 2016. Also, the Dodge Dart production ended Sept. 2016. Sales sucked on both cars, and they are no longer produced anywhere.
