“The National Highway Traffic Safety Administration [NHTSA] has released the final rule for the Car Allowance Rebate System, the $1 billion Federal program that will help consumers purchase a new, more fuel-efficient vehicle when they trade in a less fuel-efficient vehicle. Consumers could receive a $3,500 or $4,500 discount from the car dealer when they trade in their old vehicle and purchase or lease a new one. CARS will run until Nov. 1, or until the funds are depleted.”
