Depreciation value is that sum of money which accounts for the decrease in the fair market value of your motor vehicle as the direct result of having been damaged in a collision even taking into consideration that your vehicle is repairable or is repaired. Deprecation is a very uncertain and subjective area and usually only applies to newer model vehicles. The amount of depreciation will also depend on the severity of the damage. If there is minor damage there probably is no depreciation. On the other hand, the more severe the damage the more likely depreciation is present.
