Default 17C formula does not apply to our cars

So, the insurance companies are not just pulling a number out of their @ss and unfortunately the number is usually not a large amount.

I would find out the formula the insurance company followed, and the multipliers used...then go from there!
The 17C Formula is not applicable to individual vehicles. It was applied in a class action matter for the ease of determining lost value on a class wide basis.

Long and short, insurance companies try to apply it until they get push back.

May want to watch this recent Porsche Club of America video on Diminished Value.
