Your insurance will elect to replace your vehicle or reimburse you for the ACV in those instances where the vehicle is economically impractical to repair.
A vehicle is considered economically impractical to repair, or a total loss, if the cost to repair the vehicle equals or exceeds the vehicle’s ACV on the date of the loss. In many instances an insurance company will total a vehicle if the appraised damages equal 80% of the vehicle’s ACV because often, once repairs are begun, additional damages or “hidden damages” are found which would render the vehicle a total loss by definition. (This is sometimes referred to as a “constructive total” loss).
