Before making your final decision about purchasing a car with a salvage title check with your insurance company to make sure they will insure it. Some insurance companies will refuse to insure this type of titled vehicles while others might insure it but only with liability coverage and not comprehensive or collision.
States vary on how they deal with salvage titled vehicles as well. Some do not allow them on the roads without being changed into a rebuilt title. This might be what happened with this vehicle since it passed inspection and has a new VIN number. If your insurance company will insure this vehicle you should definitely get a copy of the inspection to have on file.
