"In my journey to the end of night, I must rely not only on dialectical paths of reason. I must have a good solid automobile, one that eschews the futile trappings of worldly ennui and asks only for basic maintenance. My Dodge Dart offers me this elemental solace, and as interior parts fall off I am struck by the realization of their pointlessness. I might not know if the window is up or down. It is of no consequence." -- Jean-Paul Sartre
It's a damn shame when very special cars are forgotten over time, lost in the shadow cast by their many mediocre brethren; J-P Sartre's philosophic waxing about the awful Dodge Dart, for example, did no favors for several of its legitimately fantastic variants. Others are simply unappreciated in their time, collateral damage from marketing that missed the mark, while some are too-soon condemned to cancellation by a changing economy.
This is for them: the muscle cars that haven't (yet) gotten their full due praise. You might be able to debate what constitutes a muscle car, but any one of these would rightly take a prideful place in a collector's garage.
