Following the House vote Friday to rush $2 billion into the now-popular but financially strapped Cash for Clunkers car purchase program, regional auto dealers seem optimistic the program will stick around and continue to stimulate the auto sales industry.”We’ve done 10 deals through the Cash for Clunkers program. It has drawn a lot of traffic and brought a lot of people in,” notes David Sperau, president of Trophy Ford of Forsyth. Called the Car Allowance Rebate System, or CARS, the program is designed to help the economy and the environment by spurring new car sales. Car owners can receive federal subsidies of up to $4,500 for trading in their old cars for new ones that achieve significantly higher gas mileage. Drivable, insured trade-ins that get 18 miles on the gallon or less are accepted. The dealer will take a clunker and send it off for crushing in ex-change.And if the full inventories at lots like Cronic Chevrolet, Buick, Nissan, Cadillac and Chrysler Jeep in Griffin are any indication, the program is allowing for business to be up over this time last year.
