I am looking at 2 2005 vipers one a yellow or the other a Copperhead. Which do you think would be the better choice. I have only seen the Copperhead paint on the Internet, I have a better idea of what the yellow looks like in person. I know the Copperhead was made in limited numbers (300 I think). Please let me know which you think will hold its value better or which color car you prefer. Thanks in advance
