Throw them out if they are generic 50 state. In my experience, NADA, KBB, Edmunds, et al are values of vehicles in someone's driveway in Springfield, Ill and become fiction determining the value of California vehicles, which range anywhere from $2000 to $5000 more than other States. Even a beater, in very poor shape, with 200,000mi will cost you $2000 in California. A new car here will cost 5-7K more than one bought in the Midwest.
