I'm trying to do the math on the cost of ownership of the Tesla Model 3. I'm factoring a 10% depreciation per year from the price I paid for it if I put on ~7k miles per year. I plan to keep the car for about three years, according to my math it will be worth $36k around that time. I'd really like to hold out for the dual motors/white interior but I really want the $7500 tax credit, my delivery window is April-June and I don't want to risk losing the full credit. What are your thoughts, am I too conservative or optimistic with the depreciation amount?
