To prohibit vehicle makers from preventing a dealer from tacking on extra "document preparation" fees. The bill amends a law that empowers the state to enforce exclusive new car dealer “territories” and regulate the terms of commercial relationships between dealers and manufacturers. The Senate added a provision to prohibit marketing cars made by a particular company except through a dealer in the state that is "franchised" by the manufacturer to sell and service its cars. Reportedly this is Michigan's contribution to a campaign by incumbent automakers to restrict direct marketing to consumers of electric cars made by the Tesla company.
