Vehicle Diminished Value

How It Works

The DVASSESS System For Vehicle Diminished Value Assessment Takes Into Account Real-World Market Forces

Development of the DVASSESS vehicle diminished value system began in 2006 by professional vehicle appraisers with over 30 years of vehicle appraisal experience. It’s based on having completed over 20,000 vehicle diminished value assessments, conducting over 250 interviews with vehicle sales managers, wholesalers, and auctioneers, and reviewing information from over 1,000 online consumer surveys. These surveys indicated consumers’ attitudes regarding damaged and repaired vehicles and how much of a discount they would require in order to purchase a previously wrecked and repaired vehicle.

Step 3: Detail Accident Information

Share specifics about the accident, including the date of damage, cause, point of impact, repair status, total repair cost, structural damage, and prior accident history.

Step 4: Enter Vehicle Information

Enter your vehicle’s 17 character VIN, pre-accident vehicle condition, mileage, and color. Your VIN # is then decoded by Black Book to accurately identify your vehicle.
