Total loss valuation in Illinois
The Total Loss Report for a crash in Illinois uses recognized industry valuation guides and an adjusted comp worksheet, set against the insurer's actual cash value offer. It comes with a demand letter you send in your own name, with your Alden Vehicle Report attached. A repaired car is the Diminished Value Report instead. The law is not the same everywhere. What follows is the part that is specific to Illinois, written narrowly on purpose. It is about property-damage timing, which covers both a fight over actual cash value and a diminished-value claim after a repair.
Tax, title, and registration on a total loss
For a vehicle registered in Illinois, the Total Loss Report uses this tax rule: 6.25% state vehicle use/retailers' occupation tax (35 ILCS 120/2-10 & Ill. Admin. Code tit. 50, § 919.80(c)). On a sample pre-loss value of $23,700, that is $1,481 in tax + $306 in title and registration fees = $1,787. The demand letter asks the insurer to address that amount.
If this became a lawsuit
Limitations period cited: 735 ILCS 5/13-205 (five years).
Illinois gives five years for damage to real or personal property under 735 ILCS 5/13-205. Injury to a person is a shorter, separate period. Do not time a car's lost value on the personal-injury clock, and do not assume five years applies to a contract claim on your own policy.
About five years is the period people cite for a property-damage lawsuit in Illinois. Most diminished value demands are sent to an insurer well inside that period, without a lawsuit. The period is a backstop. Claims against a government vehicle can have a separate, much shorter notice rule.
First-party and third-party
In Illinois, diminished value is most often presented as a third-party claim against the at-fault driver's liability insurer, after the car has been repaired. That is a property-damage claim. It depends on fault, on the proof, and on the policy that sits behind the at-fault driver. It is not automatic.
There is no nationwide rule that your own collision coverage pays diminished value once the repair is done. Many personal auto policies limit the insurer to the cost of repair or to the actual cash value of a total loss. Read the limit of liability in Illinois before you ask your own insurer to pay stigma value. This page does not invent a Illinois Supreme Court holding either way.
What the packet usually contains
What usually goes in a Illinois packet is ordinary, not mystical: the VIN, the mileage at the time of loss, the repair invoice with a total, photographs if you have them, the claim number, and a short statement of the amount you are asking for and how it was built. Illinois's insurance department accepts consumer complaints about claim handling. Alden does not file those complaints, and a complaint is not a substitute for the valuation.
The total-loss report fee is $300. The free check on the home page is an illustration, not this report. Nothing on this page is a statement that an insurer in Illinois must accept a formula, a tax rate, or an appraisal demand.
