This is a direct quote from a guy named "Paul Canizzaro" who say he worked on the D Dart project at Chrysler until it was finished. Paul says, "We argued that we should not produce a half-baked project, but somebody up there in the head office wanted the cars out there. Really it was cover your butt project. Though there are claims that 50 cars were produced in April of 66', the truth is about 25 or so were built. To this day, I have only seen (2) D-Darts race. "
That is from the web page that David Lee posted the URL for. Lots of imformation and pictures of D Darts there.
