Something is bothering here since your car wasn`t involved in an accident. They mishandled it. Why should you take any loss? The way I see it, there are 3 parties involved. The dealership, the dealership insurance, and the lift manufacture.
Another point is, what is the actual book value of the car shoul you actually total the car vs what it would sell for. I don`t understand where the dealership is coming up with the number $17,600.
Out of 62,000 people out there who read this thread, are there any lawyers out there willing to make a stab at this. At least open up and give us little people a hint as to how to rememdy this. "PLEASE????"
