Rail26, get an appraiser to come look at your car. Type in diminished value in google and a bunch will show up. Here's an eg. of what a major insurance company gave me.
Their 1st offer~$500.
My appraiser's~$2100
Their 2nd offer~$1500
My tenacity to get what I was owed~ $2100.
Let them know how much MSRP is for this car, how porsche driver's are anal about their cars, How this hit would deter any future potential Porsche buyer, etc.... G'luck
