What does rebuilt salvage title do to value of car?

A rebuilt salvage title is issued when a vehicle has been declared a total loss. When that happens, the original title is "retired", and the salvage may be sold--often by an insurance company that paid the owner and acquired the salvage.

As a way of recovering some of what it paid, the salvage will be sold by the insurer. The buyer of it may then repair the vehicle to make it road-worthy. The repaired vehicle is then issued a rebuilt salvage title in order to be "legalized" and used as a vehicle.

The fact that it has a rebuilt salvage title will generally reduce the value of the car, because any buyer will know that the vehicle has at one time been totaled.
