Try to find as much as possible info for the car you are considering. A proper seller will have pictures before and after so you can see for yourself. Some of the salvage cars are bad some of them are excellent. Here in SLC there is a dealer that sells only salvage cars. He was selling recently new Accords with between 50 and 200 miles on them for 7/8 thousand less than the dealership. The "issue" with them was that during the transportation on a train they've left 60 of them with some of the windows open so they were very dusty inside. The dealer rejected them and the Insurance company paid off and sold them. He got the whole lot, cleaned them and resold all inside a week.
