The climax of "The Gold Cadillac" by Mildred D. Taylor is when the family faces racial discrimination while traveling through the South in their new gold Cadillac. The tension builds as they are stopped by police and confronted by racist attitudes, culminating in a moment where they must decide how to respond to the injustice they face.
Lois is angry with her mom in the book "The Gold Cadillac" because her mom buys a gold Cadillac without consulting her father, which goes against their family's principles of hard work and saving money. Lois feels that her mom's decision is irresponsible and reckless, leading to a conflict between them.

The car company Henry Ford had begun before the current Ford Motor Company had failed and gone bankrupt without having built a single car. The bankers that had financed it sent in Henry Martyn Leland to estimate the value of what could be sold off to try to make up for the losses.

He proposed to the bankers that instead of selling off the assets of the failed company that the company be reorganized and that it first product be the Ford designed car in those plans.
Thus the first Cadillac car was a Ford designed car that Ford never built, equipped with an improved engine designed by Leland.
