OMAHA, Neb. (AP) – Two people who authorities believe helped sell more than 200 Hummers with phony titles and export many of them are now facing federal fraud charges.  FBI agent Andy Thomure said Wednesday that a former salesman at the Omaha car dealership that sold the Hummers has been arrested.  The other person charged is a woman who owned an Overland Park, Kan., trucking company. She hasn’t been arrested yet.  Many of the vehicles sold by the Huber dealership in 2005 and 2006 were bought by a small broker in Chillicothe, Mo. Most of the Hummers were resold overseas and exported to Nigeria, Germany, Canada, Japan and elsewhere.  The fraudulent titles allowed the buyers to collect incentives from General Motors that weren’t available to anyone buying more than five vehicles.
