This seems like an unfair comparison. While people buy new Porsches and Jaguars when they need them I think a lot of people have been buying Tesla because of the novelty.

This doesn't make this any less impressive, but I am not sure that it is fair to make the comparison of a company which needs to generate novelty year after year (like Jaguar and Porsche) with an entirely novel company (like Tesla).

If Tesla was putting out yearly models than this would be much more news.
