Part of my job is to process total losses and I often have to value vehicles that were previous totals that were rebuilt. It does not always cut the vaue in half and often does not depending on the vehicle. I can tell you that vehicle age, type of vehicle, market area, quality of repairs, (repairs visible from exterior, repairs visible from interior, repairs not visible) and condition of vehicle are all factors in the current value of a vehicle with a salvaged title. We use Autosource which values millions of vehicles each week nationwide and they certify and guarantee their calculations and values. Auto dealers use more of a rule of thumb and seem to treat every vehicle with a salvage title the same. You can't tell me that 2 similar vehicles both with salvage titles where one was repired horribly and is an obvious repaired total would have the same deduction as a vehicle with high quality repairs and not visibly repired would have. What about a flood vehicle with a salvage title vs a vehicle that has had a full body section? If you were looking to purchase a vehicle that had a salvage title would you be willing to pay the same amount for one of these vs the other? Like I said there are alot of variables that factor in to the true ACV of any given vehicle.
