Sandpebble Beige, love it or hater it?

Go with the original beige color. I had a 69 Coronet 440 that was beige, the only one like it I ever saw, (wish I had kept it).
Have you research the build numbers for that car with that color? It just could be that its much more rare than you think and thus, much more valuable in the original color. My sons 74 Dart Swinger is original "Avacado Gold Poly", which is basically an olive-green. Not a color everyone thinks about useing but one that gets comments at the shows since its the only one. Too many reds, blacks, and blues out there already!
