As a side note, if buying from a salvage auction ( like Copart ) pretty much never buy from a seller that isn't an insurance company or maybe a new car dealer. Some brokers buy wrecks at salvage auction, quickly hang a few parts on the car to make it look like a light hit then flip it.

Have a look here, this guy isn't a professional body guy but does make some very valid points.
