NigelM,
I guess the third answer "No" is there to get an idea about what percentage of owners are getting the letter. However it should clarify this answer applies only to owners. The third answer should be "No, but I own a Model S". Otherwise what is the point of the third answer. I don't know if polls can be edited. If it was me, and it can't be edited, I would ask this topic to be removed and do it again.
