Can I sue the insurance of the one hit my car or sue his insurance because of the loss value of my car?

You don't sue the ins. co.; you sue the other driver, and the ins. co. defends him/her.

The insurance company merely agrees to pay up to a certain sum for the person responsible for the accident, it is not liable for the accident. So you have to sue the individual who caused the damage. Technically, loss of value of the vehicle is recoverable, but insurance adjusters are loath to pay for it. You need to get information from several car dealerships as to how much of a decrease in the sales price of the car results from having to reveal it was previously involved in an accident. You have to be very stubborn and professional appearing in arguing this as the adjuster will not want to pay. Be sure your demand letter does not have any sentence errors.
