The value of your car does affect the cost of registration, but it is not generally possible to determine the car value by registration. Car value is determined through the use of comparable vehicles, and these are available in databases as well as industry publications. One such publication is called Kelley Blue Book. The value in the Kelley Blue Book will be determined by the vehicle’s condition. There will be values listed for suggested retail value and that value may be further broken down into condition categories: excellent, good, or fair condition. Different prices are listed for private party sales versus dealership sales, as well.
