The predecessor of Cadillac was the Detroit Automobile Company, whose owner was actually the current owner of Ford Motor, Henry Ford. However, due to disagreements with two other investors at the time, Henry Ford decided to leave Cadillac Company and start his own Ford Motor.
At that time, Cadillac's full name was Henry Ford Cadillac Company, but after being acquired by General Motors, Henry Ford was removed from the name, leaving only Cadillac!
As one of the many brands under General Motors, Cadillac is now positioned in the market as providing luxury cars!
This is actually the reason why Donnie wants Cadillac.
Although luxury cars appear to be high-end, in reality, regardless of the time period, the sales of luxury cars are never as good as regular cars. Ford Motor, now the top-selling in the U.S., is the best proof of this.
So Cadillac's position within General Motors is not comparable to that of Buick.
