I would be curious to see how many model S owners would buy another Tesla now vs before the infamous updates last Spring. I know I was considering an X for my wife to replace our truck. After the update I put those plans on hold. Then my S was totalled and I bought a new Accord instead of another S or a new 3. If my S had been totalled before the updates I am confident I would have replaced it with a new 3.
Unless something changes, I am in a bit of a quandary in a couple of years when I look at replacing my S. At the end of the day, my trust in Tesla is deeply shaken. As early adopters, we knew we were getting science projects, so I have less of an issue with tech not working quite as planned than I do with Tesla's subsequent handling of the issues. I no longer trust Tesla to do the right thing anymore. They have shown they are more than willing to act unilaterally for their benefit. I would dearly love to replace my S with another Tesla, but I work too hard for my money to continue to hand it over to a company that does not respect me as a customer.
