Have searched and read other postings that I can find and would be interested in getting additional input. My situation: leased an S85D Midnight Silver, all options (except last row), panoramic roof, MSRP $101k. Will be at 45k miles at 2 yrs of ownership, which is fast approaching. Window to consider changing to S100D seems optimally to be just before 50k miles (assuming I Were to buy extended warranty at 50k). So, I've asked for a buy-out price from Tesla. My lease is with Tesla, and can be terminated early. I asked an OA if I could roll the remaining months into a new lease and was told Tesla doesn't do this.. My estimate is that I will be at 50k miles with about 10 months left on the lease, best case 9 months. Would be interested if others have trod this path already and if so, what was your experience? Did you step out of the lease into a new car, or just finish it out and pay the overage? Also curious if the buyout (outside of mileage overage) was a lot more than the remaining lease payments (I will have that number soon enough and will be happy to share my data point for the next person). Thanks.
