Total loss is usually 70% of value. But that is not always the case either and esp when dealing with cars of these values. This car when wrecked would of been a total loss cause they were not worth what they are now and would of been well over 150k to fix it.Salvage happens when the cost to repair is above a threshold (say 1/2 the current value, but it can vary depending on other conditions like air bags deployed). If it wasn't totaled, then the owner could have taken the settlement (knowing it wasn't enough) and pocketed the cash. It can turn on you. My daughter had hail damage to her car but didn't get the repairs (took at as a "diminished value".) Insurance company asked for evidence of repair and since there wasn't any dropped her... It was the AAA company.
I've never heard of an insurance company asking to see if a repair has been done in my 30 years of working in the industry.. Even if she did not do the repair it could be noted that the car was un-fixed for future claims.
