Is this statement even close to being true that "only about 30 M-Code Darts still exist":

Assembled as a run-of-the-mill 383 car, then transformed into a 440-powered strip streak by the Hurst-Campbell Corporation, this Dodge is one of only 640 M-code Darts produced for the 1969 model year. Most of those big engine warriors were sold to drag racers who needed something tough to whip at the track and, as a result, Chrysler expert Galen Govier estimates that only 30 still exist.
