If it is a numbers car, it would hurt the value.
If it's a non numbers car and it is painted a high impact, black or cool custom color ( likr Red & Rev's ) the value goes up.
if it is a non numbers car and it is painted poorly or some dorkey color, it hurts the value.
If it's painted like Choppintime's it's a toss up, Some people wouldn't pay as much, others, like me, like that old school, the painter wasn't wearing a mask, psycadelic paint schemes. I'd fork over more dough.
