A politically connected businessman was sentenced to more than five years in prison Thursday for stealing hundreds of thousands of dollars in financing on luxury car leases at his suburban leasing agency. U.S. District Judge Harry Leinenweber handed down a sentence of 63 months for Marc Zaransky, a former consultant for CAR Leasing in Lincolnwood who pleaded guilty last year to charges alleging he defrauded creditors of about $2.5 million by misrepresenting how the money was used.
