SUN VALLEY, CA - AUGUST 7: A crushed Isuzu Rodeo, that was turned in through the Cash for Clunkers federal program, lies near a car crusher at the Aadlen Brothers Auto Wrecking junkyard on August 7, 2009 in Sun Valley, California. The Senate voted 60 to 37 for the approval of an additional $2 billion funding for the popular auto rebate initiative that offers consumers $3,500 to $4,500 to trade in their older high-mileage vehicle for a more fuel-efficient one. The additional funding means that another half million vehicles can be purchased, providing an increased boost to the sluggish auto industry. The program had created such a demand that some locales are reporting shortages of popular high-mileage models like the Ford Focus and Toyota Prius. Under the program, dealers are instructed to replace the oil of the trade-ins with a solution of sodium-silicate and water and run the engine until it is damaged beyond repair. Critics charge that auto parts recyclers and charities that rely on old car donations are being hurt by the policy. (Photo by David McNew/Getty Images) Photo: David McNew, Getty Images
