Tesla does not have a good record of repeat customers, either. People who buy a new car every year are not buying a second Tesla.
I call bullshit. While standing in line to reserve a model 3 in Denver, I was surrounded by Model S owners or extended family of an S owner, and a few Leaf owners. I saw a Roadster drive by, presumably looking for a parking space. From that experience, my wag is 10%, maybe 15%, were repeat customers.
