A five-month investigation into the self- proclaimed "World's Largest Chevy Dealer." Hearing complaints from customers in Middle Tennessee after they bought cars from the Bill Heard Chevrolet dealership, an investigation found similar complaints in other states. NewsChannel 5 examined sales contracts and loan documents of customers and compared them with documents that had been submitted on their behalf to lenders by the Bill Heard company. The reporters found that the personal and financial information had been altered so loans would be granted. After the story was aired, the Tennessee Attorney General and the state's Motor Vehicle Commission regulators opened an investigation. The investigation is on going.
