It's a damned if you don't and damned if you do. i personally think both cars are very nice, perhaps the Dodge is more rarer, but in all honesty you both thought you had good cars and you did. As far as trade value i don't know which car would have brought more more money at an auction. but in reality you made the trade dark or day light and i think you should consider it a mistake if that's the way you feel and learn from it. i personally think the Camero will be more valuable, if #'s match if you sale it at an auction, even if you have to repaint it.
