Well. Here's my plan if mine gets wrecked. I've read here and TM that it can take easily 6 months or more before a well-wrecked Tesla is fixed. Talk to my insurance company - an the other insurance company.. Either my insurance or the other will be paying for a rental. I am sure they know it takes a while - months to get a Tesla fixed. Do they want to pay for months of rental car for me? I will try to get them to give me a lump sum settlement for just the rental car part separate from the accident. If I can, I can use it for a down payment on a used Tesla to drive while mine is in the shop.
If they total mine, then I can use the used on and trade it in. While mine is wrecked and in the stop, I am pausing insurance on the wrecked one. Sure don't need it sitting in the shop.
Then, find a used one maybe cheap one. Maybe at an auction. Maybe buy a used Tesla trade-in from Tesla before they sell it to the auction. Find one, and buy it with as little down as I can, maybe the cheapest I can find, or maybe one like I have before it was wrecked. Be flexible. Drive it and make payments until mine is fixed. In the mean time, work on making the used one better looking and nicer looking than it was when I bought it. Clean it. I am going to try to sell it months from now for at least what I bought it for. And when I get mine back, if its not good, I am going to sell or trade it to get back where I was before. Not going to try and cheat anyone, but put my energies into still driving a Tesla while I wait on repairs.
Once I am back in a Tesla, I can let my insurance company and/or the other insurance company figure it out, fight it out, but I am now in a better position versus at their mercy to give me what they want to give me because I am no longer in a rush to settle so I can find another car.
