If you are a fan of classic american cars made by General Motors, you need to take a look at this video.  The video takes you on a tour of some of the most memorable cars made by the company, it features everything from Corvairs to Corvettes, the first GMC truck to electric cars and much more.  Some of these cars were instant classics and some not so good!  It's fun to see some vehicles that never made it to showroom floors, like the hydrogen powered van.
