Auto retailer CarMax is urging Congress to include used vehicles in its "cash for clunkers" legislation.
Lawmakers have been trying to develop incentives to help the auto industry and respond to environmental groups that want better fuel efficiency in the vehicle fleet.
The proposed program would provide vouchers to consumers who trade in their gas guzzlers and buy more fuel-efficient vehicles. The bills are designed to get more gas-sipping cars on the road and boost auto sales.
Some versions of the legislation provide vouchers for used vehicles, others do not.
Richmond-based CarMax says including used vehicles in the program will help further promote fuel efficiency, save jobs and help more people afford a car.
