What metaphors are used in The Red Convertible by Louise Erdrich?

The author uses the literary techniques of similes and metaphors to help describe Lyman's feelings and observations. When Henry is going away to the Marines, Lyman states that Henry is only wanted for his Indian nose "big and sharp as a hatchet..."

When Lyman describes the condition of the red convertible after he has beaten it up, he says, "By the time I was done with the car it looked worse than any typical Indian car that has been driven all its life on reservation roads, which they always say are like government promises - full of holes."
