1938 Buick Y-Job Concept Car

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.

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