1951 GM LeSabre Concept
You've certainly heard of the BUICK LeSabre, but did you know that the original concept was branded under the umbrella GM name? The large rounded nose and tail of the futuristic concept make it look like a jet turbine with a body built around it. At a time when cars had fins and rear wings bigger than planes, this seemed like an appropriate build. The project was headed by Harley Earl, head of GM styling at the time.
