Cash for Clunkers
Our results of operations for 2009 were favorably impacted by the Consumer Assistance to Recycle and Save Act of 2009, commonly referred to as cash for clunkers, that was enacted at the end of June 2009. Under the cash for clunkers program, which officially began in July 2009, certain new vehicle buyers who traded in less fuel-efficient vehicles were eligible for a credit of up to $4,500 from the federal government.
Cash for clunkers stimulated consumer demand for new vehicles, and we sold approximately 12,500 new vehicles under the program. Since new vehicles with a manufacturers suggested retail price above $45,000 did not qualify under the program, and since each new vehicle sold had to be more fuel-efficient than the related trade-in vehicle, cash for clunkers disproportionately benefited sales of smaller, more fuel-efficient vehicles, primarily in our Domestic and Import segments. Cash for clunkers officially ended on August 24, 2009.
