Posting this in the Model S section because I think it will get the most response. I've been lurking on TMC for a long time, am a big Tesla fan, and recently joined here because I will be making the plunge into the EV world soon. I'm also a bit of a data nerd, and have been following the EV-CPO site since the huge sales in the 3rd quarter of 2016. Now that the 4th quarter is behind us, I noticed that the CPO car count (being shown) is much higher now than it was at the end of Q3. This makes me think that there are a lot of folks who are trading their current Tesla for a newer one. Lots of speculation here and on other sites that Tesla doesn't always show a complete inventory picture, so there could be other explanations too. I've read many posts where folks compare their current car to an earlier one, so I'm trying to get a feel for how many people either currently own or have owned multiple Teslas. Have you owned multiple Teslas, either simultaneously or back to back?
