What will the insurance pay on an '85 BMW that caught on fire?

The Actual Cash Value (ACV) or fair Market value is determined by several factors, i.e. 1)geographical area (what your vehicle is worth in San Francisco will be different than Dallas; 2)physical condition of your vehicle; 3)mileage; 4)is your vehicle restored? new paint,new engine, interior? What I always would tell the insured is to always keep records and have recent photos of your vehicle. The companies most used to value your vehicle are ADP and CCC. Request a copy of this valuation and review it for correctness. Challenge what aspects you feel are incorrect.
