Here is my take on damage history. Growing up we were poor. We built one pickup out of several, Cars the same way. I still rebuild a lawn mower or other item from a damaged or scrapped item. If everything is repaired properly it is not an issue. Most real repairs turn out as good or better than the factory.
When you are involved in a car accident do you repair it or throw it away? If damage history scares someone that much then you should throw it away and buy new. I personally do not have an issue with this if it is done properly. Drilling holes to stop cracks or pop rivets to hold it together won't fly in my book.
