Ask the seller. Ask them to reconcile the information sources. If this car was in an accident, declared a total insurance loss, then its value is 50% or more less than the kbb or edmunds values, which assume no salvage title.
I interpret the report as saying that even though no insurance loss was reported (no insurance company is compelled to report losses to these data sources), a salvage title was issued.
To me, this is a major buyer beware situation unless you know cars well and know what to look for in a rebuild salvaged car. It is not worth any published book value because of the salvage title.
