Like Dr John, I've wondered if Exner was losing his touch for what was a commercial design. And yet, in mid-1960, 15 months before he was fired, when the S-series was one year from its intended release, Exner was overseeing the shaping of what we know as the 1963 AP5 Valiant (aka 1963 American Plymouth Valiant and Dodge Dart). The photo of the Australian Valiant prototype I used in the story was dated October 1960, and the one here is dated August 1960. Note the label Australian Plymouth 5 (AP5?). The shape of the AP5 and its US counterparts (also pictured) is so different, so restrained, from the first Valiant and S-series cars, that it says to me that Exner was indeed searching for a new direction, and these cars are the evidence that he was well on his way to finding it. But then he was fired and we will never know what might have been. It is interesting to see just how solidly mainstream Exner shaped the 1963 Valiant/Dart, when compared to the 1962 Chevrolet.
