I feel the same way about cars on this too. So what if a vehicle was in an accident? If it was fixed right most folks will never know and unless you have a very well trained eye its hard to know at all.

My uncle has a shop for over 27 years and repurchased wrecked cars from the auctions for a while, professionally repaired them and were able to sell them. It says a lot that I still see the same customers and in some cases the same car coming back since I was a kid. We always informed the purchaser of the repairs however so I would be concerned if the seller isn't up front with the information.
