How does Louise Erdrich use imagery in The Red Convertible?

The imagery can be seen in the symbolism below:

Erdrich uses numerous symbols in "The Red Convertible" to convey meaning and to communicate complex ideas. The title of the story points to the most fully developed symbol in the story, the car. The car is a complex symbol because its meaning changes as the story progresses. It represents the connection between Lyman and Henry. They buy it together on a mutual impulse, and then they take it on a summer-long road trip together. Twice Henry tries to give Lyman full ownership of the car, but Lyman refuses because the car symbolizes their union. In the end, the car is the literal vehicle that takes the brothers to the site of their tragic last meeting. Once Henry is dead, Lyman knows that he has lost his innocence and his connection to his brother, and, therefore, he has no use for the car.
