Diminished value of your vehicle is recoverable in third-party cases only. You can only recover from third-party at fault insurance companies and you cannot make a claim under your own uninsured motorist insurance. There is NO mandatory insurance law, and the statute of limitations is 3 years from the time of the accident. Section III-43-page 18.
