1970 Chevrolet Chevelle & more on display at GM Heritage Center

In this video, GM Heritage Center general manager Greg Wallace shows off some of the collection's most notable cars. The Cadillac Sixteen Concept shares floor space with a V16 Cadillac, and Bill Mitchell's Mako Shark sits fender to fender with its Chevrolet Corvette progeny. For a General Motors nerd, it's heaven.
