Note to Linda S. Jolly ...
The first thing that you have to do is call a Salvage Yard, and ask them if they have a door that will match your Make and Model car. On a Liability Policy, the company has the option of Repairs or Replacement up to the ACV of the vehicle. If the salvage door is less than the "Total Loss" ... you don't need to get a salvage title. You just buy the door. Then have some body shop hang it on the car. It might need some paint on that door to match the rest of the car. Door, plus labor, plus paint is the extent of your claim.
That should not be a total loss, unless the door pillar, roof panel, or rocker panel under the door, is buckled. If you have any other old damage on the car that you never got fixed, those amounts get subtracted from the Book Value of the car.
Imagine having a $10 bill in your hand, and burning it with a match. That's a TOTAL LOSS, and you don't get Car Rentals to go to the bank, or to work, to get another $10 bill.
