The grey market was successful enough that it ate significantly into the business of Mercedes-Benz of North America and their dealers. The corporation launched a successful million-dollar congressional lobbying effort to stop private importation of vehicles not officially intended for the U.S. market. An organisation called AICA (Automotive Importers Compliance Association) was formed by importers in California, Florida, New York, Texas, and elsewhere to counter some of these actions by Mercedes lobbyists, but the Motor Vehicle Safety Compliance Act was passed in 1988, effectively ending private import of grey-market vehicles to the United States. There have been allegations of improper lobbying, but the issue has never been raised in court.
