A totaled vehicle will get branded! Meaning it will say a total loss and rebuilt on the new title that will be issued. It could bring down the value of your car. Which is another benefit to having a Porsche Mechanic there to "represent" you when the adjuster is looking at the car.
History isn't such a bad thing due to this forum. You have pictures and a story to tell. THe truth is okay if the title is branded due to the label generated by the Insurance company. After you get the settlement and the TOTALed settlement; you can buy back the equipment. That is when the new title is issued.
Buy it back and build it back! It is just another story for your 914's life. I have seen other cars out there who have much worse damage and stories to tell. Your's just has a collision chapter in its story.
Sucks, but you will get through it!
Another thing to argue is how can a person NOT see a RED car? What the heck was the woman looking at? GHEZ!
Good Luck!
P.s. aren't you grabbing your neck too!? "OUCH, I can't move and need therapy to get my life back together." I see that ALOT! It's called "soft tissue damage" and Insurance just pays.
