Buick Y-Job
The Buick Y-Job is the first concept car — a 1938 Buick convertible built to test design ideas, not sell units. Designed by Harley Earl, it used a Buick Super chassis and featured power-operated hidden headlamps, electric windows, and styling cues that defined Buick for decades. It became Earl’s daily driver after public debut. It changed how mass manufacturers develop cars: by treating design as a public-facing experiment.
