But these days, Worthington isn't on a car lot, he's in a courtroom. The 92-year-old is in the middle of a bitter divorce from his fourth wife, Anna Worthington.
The 41-year-old singer from Iceland filed for divorce back in December 2011, after only eight months of matrimony. Her attorney, Mark Vincent Kaplan, says she is entitled to half of a $3-million mansion in Beverly Hills that Cal Worthington purchased during their short-lived marriage.
"She should be able to receive at least half those proceeds, because it was supposed to be a community loan and on a community obligation," said Kaplan.
But Cal Worthington disagrees. During Thursday's closing arguments in Los Angeles County Superior Court, his attorney, Stephen Kolodny, said Anna Worthington signed a prenuptial agreement, which only entitled her to $30,000 in spousal support.
Kolodny also alleges that the singer took more than $200,000 from accounts she shared with her husband and then diverted the money in private accounts. But Kaplan said his client never had any spending restrictions.
"There was a joint account into which Mr. Worthington placed funds for Mrs. Worthington to use however she wanted to," said Kaplan.
At 92 years old, Cal Worthington says his fans still recognize him and call to him by name. But he admits that the divorce, which has been more than a year in the making, has taken a toll.
"I wouldn't wish this on anybody," he said. "This divorce thing is horrible."
He didn't want to talk about his soon-to-be ex-wife, who refused to grant us an on-camera interview. But the retired car salesman said he is looking forward to putting this chapter of his life in the rearview mirror.
A judge will make a final ruling on the divorce within 90 days.
