12. Chevrolet Vega Panel Express

The Chevrolet Vega Panel Express was Chevrolet’s compact solution for small business deliveries, competing directly with the Ford Pinto Panel. Its car-based utility and practical design had promise, but notorious rust problems and persistent engine woes doomed its longevity.
Very few Panel Express models survived the decades, with most succumbing to the elements. Today, this humble workhorse is all but forgotten, its once-common silhouette now a true rarity.
