If you are attempting to recover damages as a result of diminished value, you will undoubtedly be required to prove your loss.
This can be very difficult for the average accident victim. Can you just call around and get auto dealer quotes to prove your loss? Knowledge of the proper methodologies and form for presenting valid supporting data eludes most laymen. As a former licensed adjuster and current owner of a claim services company, I can attest to how hard it is to document diminished value in a credible manner.
