How does the author use foreshadowing in Alas, Babylon?

The description of Randy's car stops amazingly short of being complimentary. Through his use of personification, the author tells us that the new car is a gas guzzler...... foreshadowing its future uselessness.

"Randy got into his new Bonneville. It was a sweet car, a compromise between a sports job and a hard top, long, low, very fast, and a lot of fun, even though its high-compression engine drank premium fuel in quantity."
