GM’s financing programs will expire April 12.

General Motors said its current 7.7% and 9.9% annual financing rates on a variety of cars and small trucks will end at midnight Saturday, April 12. When the program was announced Feb. 24, no expiration date was set. The auto maker also said that it will begin a new 9.9% financing program for the Chevrolet Nova, built by GM’s joint venture with Toyota. Industry analysts expect GM and other U.S. car makers to offer generous new incentives when current programs end to boost sluggish sales.
