i think that car would be worth quite abit, theres a guy here who owns a factory plum crazy 71 challenegr r/t 383 4-spd w/ shaker ,complete with r/t stripes,black interior,top and go wing and that car is worth tons and is most likely 1 of 1 with its options, my dad used 2 see it alot back in the late 80's, but now it sits rotting in a storage lot-MATT
