Elon just bought GM?????

From a salesman at our local dealer. I don't know if it's true but I wouldn't doubt it
I don't trust anything a car salesman says. It may be true but more than likely he doesn't know what is going on at Stellantis as far as that decision goes and really the restriction of only selling diesel trucks to buyers who prove their need is a regulatory issue handed down by government, not the manufacturer.
I would be willing to bet he is spreading this rumor to try to scare people into buying diesels this year and not to wait.
