If it was me I would tow the thing out of the storage lot where it is accuring fees and take it to my house. Then I would allow the insurance company to conduct their apprasial and see where it comes in. I would provide pre-crash pictures, similar comps, and a list of options to the adjustor. If you feel the offer is too low I would hire an independent appraiser to provide a counter price point to submit to the adjustor. If the insurance company is still too low then I would seek arbitration. I would not pay for an attorney personally. The expenses of an attorney will be too high to litigate the value of a car. Source- my family owns an insurance company and I investigate crashes for a living. LOL
