Great video from 1966 comparing Chevy to the competition. Some of it is pretty cheesy, and its obvious they purposely didn't drive well in competitor's cars (like the Mustang driver in the "sports car" part of the video), but it's still entertaining. Its obvious Mustang was worrying them, they focused a lot on putting it down, lol.

 

I think it was odd that they considered driving on rocky dirt roads to be sports car driving. That test would have been better with pickup trucks!
