Arizona Gov. Janet Napolitano said she is parking hundreds of state cars as part of her plan to trim bureaucratic fat and fine-tune government services.Several state agencies have reduced their number of state cars since Gov. Napolitano launched her efficiency review team earlier this year. Some of the agencies that have permanently parked state vehicles are:Department of Administration: 174 cars returned.Department of Transportation: 20.Attorney General's Office: 3.Veterans Memorial Coliseum: 7.Department of Corrections: 43.Department of Commerce: 8.Game and Fish: 38.State Parks Department: 1.School for the Deaf and the Blind: 22.Napolitano said reducing the state's fleet by 257 vehicles will save an estimated $900,000 and is part of a process she began in April to cut state expenses by doing more with less."We've only just begun," she said. "If we can move money from cars to classrooms, that's a very good thing. The agencies know that I'm serious. These are precious dollars that won't have to be cut from vital services that Arizonans depend on. We have to make sure we're getting the maximum bang for our buck when it comes to state vehicles," Napolitano said."The state vehicles are sold at public auctions.
