According to General Motors, rental car agencies will receive half the number of the 2008 Chevy Malibu sedans than they normally acquire with previous models, The Detroit News reports. Currently, 40 percent of the Malibu is sold to rental companies. However, GM only intends to put out 20 percent of the production output to rental agencies.In recent years, the Detroit Three have been trying to cut ties from rental-car companies because they believe that rental fleets drive down the value of vehicles by oversupplying the market, The Detroit News reported. Production for the 2008 Chevy Malibu began on Oct. 15. The vehicle’s first showcase is scheduled for Nov. 1.
