I feel for you. Sure, you can buy another one, but your equity vanished when the accident occurred.
As the owner of a 12 week old S85 that currently hasabout 8800 miles on it, and was delivered with autopilot feature, an additional question comes up for me. Should I get in an accident with it, assuming the exact same type and extent of damage as the OP experienced, and assuming a very high repair estimate that influences my insurance company to issue a similar edict, what might the hit be on mine? Certainly,I would expect the total loss value for a 2014 autopilot-equipped 85S should be higher than the ~$70K value cited by the OP, but I'm not going to be satisfied at buying one of the non-autopilot equipped vehicles. Again, I'm raising the question and it currently is not my situation, but it sure makes one think.
I don't think Elon Musk wants to be standing up at a 2015 press conference or shareholders meeting stating that new car sales have plummeted, and Tesla stock is 'correcting' itself. I don't think Tesla is that concerned about this issue of the absurdly inflated repair estimates by their authorized body shops and costs associated with a MS involved in an accident. Probably they would recommend buying a loaner or place an order for a new one. Sure, it's remarkable at the number of MS that are listed on eBay right now, and in almost all listings, the owner id ordering a new 85D or P85D. Sure follows the Consumer Reports about 98% of owners would buy another. Sure, if you don't have to blink when writing the check, a total loss might not worry you. But, if the luster goes off the car, both by returning MS owners, media, naysayer analysts, ICE enthusiasts, and even Consumer Reports when next years customer / owner satisfaction survey results come out, and the owner satisfaction plummets, every news agency will report on it, probably with the words of 'falling from grace', 'too good to last' and 'market correction'.
I also wonder if this would or could be affected by Tesla doing the work, particularly at the factory. Since I live relatively close to the factory, would the factory SC have a different cost estimate? If so, I'm not advocating shipping the patient back to the mothership, but I might have to stop in and talk with them, butg wonder if I would get a conclusive answer. They might not want to be quoted, citing a hypothetical situation, but I still wonder. If Tesla SC comes back with an absurdly high estimate, there at the factory, that would be an eye opener.
