In the mid-80s nothing could mess with the speed of a Buick Grand National. Not a Corvette. Not even a Lambo. This thing was fast. It shook the cobwebs off the Buick brand and won over enthusiasts everywhere.

And why not? It was a street legal racer hitting 60mph in 4.7 seconds.

The last Grand National was built in 1987. Now the icon gets its respect in the form of a BLACK AIR, a documentary detailing one of America's greatest muscle cars. Watch the first teaser, discussing the car's misfit status, above. [Vimeo]
