You are entitled to recover the "fair market value" or the "actual cash value" of your vehicle immediately before the accident. One common source used to estimate fair market value is the Kelley Blue Book. Other sources of information are the local newspaper or the Auto Trader, which may list the for-sale price of cars of the same make, model, and year as yours. Occasionally, an expert vehicle appraiser is used to help prove the value of your vehicle.
