Unfortunately, most of the links above no longer work. In reference to this I know that Popular Mechanics issue dated May of 1967 had and article about the comparison between the top three off roaders. Bronco, Jeep CJ, and Scout. I don't know if ebay has any left as I bought all I could some years ago. I have three left. Here's a caption under one of the pictures. "Racing up the trail, the Ford Bronco did everything but stand on end. Despite its suburban look, the Bronco took the most rugged terrain as though it were a paved highway, displaying amazing speed and maneuverability that made it the most surprising car in the test."
And no the three are not for sale. Plans are for one magazine for each of the three early Broncos I have in my stable.
