This is a favorite Tex Avery cartoon called "One Cab's Family" and we were always glued to the TV set whenever it came up in rotation. There is no doubt that the scene where the little cab turns into a speedy hot rod left a mark on us growing up! This cartoon also seems to have inspired the Pixar "Cars" series and is just as entertaining. Now it's back online to enjoy again! We seem to recall another similar story about an airplane... we'll have to look for that one, too!
