All used Chevrolets in New Jersey and elsewhere were produced by General Motors, whose CEO recently resigned.

On December 1, GM chief executive Fritz Henderson left his post, reports the New York Times. He has been temporarily replaced by the company’s chairman, Edward Whitacre, Jr.

“We all agreed that some changes needed to be made going forward,” said Whitacre, according to The Times.

Henderson’s departure meant he wouldn’t be able to deliver his speech at the Los Angeles auto show on December 2 as expected, says the news source. Robert Lutz, GM’s vice chairman, was asked to take his place.

“As you know, I’m kind of a last-minute substitute,” Lutz told the show’s attendees, one of whom was the newspaper’s auto blogger Jerry Garrett. “You may have read something about it. Like GM has been doing very little to fill the newspapers lately,” he continued sarcastically.

Henderson was GM’s CEO for less than a year, according to MSNBC. Ideally, restructuring the automaker’s management will have a beneficial effect on used Chevrolets in New Jersey and the company’s other subsidiaries.
