Hall County Sheriff Gerald Couch is proposing to upgrade his department’s fleet while saving money by having cars refurbished rather than replaced. Couch will outline the initiative to the Board of Commissioners at today’s work session. “It’s a program I first learned about last summer, where Ford Motor Co. and some of the dealerships with Ford will take the Crown Victoria and they will refurbish the car from bumper to bumper: the worn parts, the drive train, the transmission, the interior,” he said.
