Its avant-garde, aircraft-inspired design included a bubble-top canopy, a freestanding speedometer, and a rear-mounted camera linked to a dashboard display that ostensibly eliminated the need for a rear-view mirror. The two tones of its fiberglass body were separated by Buick’s trademark “sweepspear,” or the curved chrome trim along the side panels. While certain elements of its design were later incorporated into other models, only one of these cars was produced, and it is now on display at the Sloan Museum in Flint, Michigan.
