67 GTX grille
The nicest 67 X grille I've ever seen was listed for $750 and never sold for that! Very nice examples can be had for $300-450, anything with damage or needing to be restored commands much less! From the pictures, and for someone who does not have one, that would be $100-150, someone who has one that needs restored as this one does would probably not buy it for that, maybe $75!
Im afraid your customer base is somewhat limited by its condition, and the fact that there aren't that many 67 X's out there! Maybe a little more interest if it fits other trim levels!!
I'm no expert, but!!!...
