I'm new to Tesla and have deposits down for two Model 3's (I was #16 in Las Vegas). We are thinking about purchasing a used Model S, probably a 2014 with low miles. I'm seeing prices in the high 50's and low 60's. (if anyone knows the best web site to find the best deals on the Model S, please let me know!) I've been getting conflicting information about the ability for the new owner of a used Model S to add on an extended warranty. I've read that you can do it and I've read that you can't. One person told me the original owner would have to purchase the extended warranty before selling me the car. That's fine for a private party transaction, but wouldn't work if I find the "right" Model S at a dealer. Can anyone give me some accurate information, and is there a way to get an extended warranty on a used model S purchase? We plan to keep the car for a long time and feel more comfortable having the extra coverage. Thanks very much.
