Condition

• The Kelley Blue Book does not list a single price for each vehicle. Instead, it lists various prices, with each price varying according to the condition of the car. When you peruse the listings, you can see that the value of the same make, model and year of car can vary quite widely depending on whether that car is in excellent, good or fair condition.
  
  

Mileage

• The listings and values contained in the Kelley Blue Book assume that the car has an average number of miles for its age. The actual mileage of your own vehicle can affect its value and make it differ markedly from what is listed in that guide. If your car has very low mileage, its actual resale value could be much higher than what is listed in Kelley Blue Book, so you need to consider the mileage carefully when negotiating with your insurance company or setting a price to sell your car.
  
  

Optional Equpiment

• The optional equipment installed on your vehicle can greatly impact its value, so it is important to check the listings in Kelley Blue Book against the list of optional equipment for your own vehicle. If you have the original bill of sale and paperwork for your vehicle, it is a lot easier to compile that list of options. If you do not have the original list of options available, you can go through your car and note each piece of optional equipment it contains, from a CD player or satellite radio to side airbags and GPS systems.
  
  

Car Shopping

• You can use the resources and prices from the Kelley Blue Book when you shop for a used car as well. Keeping a copy of the Kelley Blue Book guide with you as you shop can make it a lot easier to get a good deal, since you will know approximately how much that car is worth before you contact the seller and set up an appointment to look at and test drive the car or truck.
