1938 Buick Y-Job

Buick called it "Y" because so many makers dubbed experimental cars "X." Styling and mechanical features of the "Y Job" showed up on GM products, particularly Buick and Cadillac, throughout the ’40s. Particularly noteworthy is the introduction of a wide horizontal grille with thin vertical bars, which remains a Buick styling feature to this day.

But dream cars, like yesterday’s newspapers, have a short shelf life. The Y-Job’s innovative styling and advanced features soon paled alongside even more futuristic products from GM’s supercharged design staff. The Y-Job was eventually consigned to a warehouse, and later transferred to the Sloan Museum in Flint, Mich. There the Y-Job languished in dusty anonymity - until a burgeoning interest in Detroit’s fanciful dream cars rescued the Y-Job and its descendants from obscurity.

As historians and enthusiasts began to appreciate the significance of these landmark vehicles, the Y-Job was returned to its former glory as the centerpiece of a concept car revival at the Henry Ford Museum in Dearborn, Mich. In 1993, the Y-Job came home to the GM Design Center in Warren, Mich., where it now resides as an honored member of GM’s heritage collection.

The car served as Harley’s Earl personal transportation for many years, until he replaced it with the 1951 General Motors LeSabre dream car.
