I have never let it bother me as I have owned a 73 Cuda, 2-73 Challengers of which one I still wish I owned as it was a matching numbers Rallye 340 4-speed black with white interior, rallye dash, console, AC, PS, PD brakes, light group. It needed restored and had been hit hard in the left front and had had frame rail work. It drove good and ran good but cars come and go. I have had 2-70 cuda's and 2-71 challenger RT's. I'm restoring a 73 B5 blue challenger right now and some parts are cheaper to buy on the 72-74 models. I say buy what you can afford and enjoy the crap out of them as these cars will never be built again. I drive all of mine and people think I'm crazy but life is short so don't let it slip by.
