Largely considered the first industry concept car, the Buick Y-Job racked up many miles before finally debuting to the media on this day in 1940. Designed by Harley Earl and company as a design exercise that incorporated technological advancement, the Y-Job acted as a test mule for many GM styling and engineering practices that later became common.
The Y-Job, built on a 1938 Buick Super chassis, featured hidden headlights, flush door handles, hideaway top, and wraparound bumpers. Many of its styling queues are found on the next generation of GM automobiles, particularly Buicks themselves.
Harley Earl drove the Buick Y-Job as his personal vehicle until 1951. It was later donated to the Henry Ford Museum, where it was restored before being returned back to GM.
