14. Pontiac Astre
The Pontiac Astre was largely a Chevrolet Vega underneath, inheriting all of its notorious reliability and rust problems. Pontiac tried to inject some excitement with sporty marketing and trim, but the Astre never truly distinguished itself.
Production ended quietly, and very few examples have survived the decades. Today, spotting an Astre is a rare event—even among dedicated Pontiac collectors.
