They are still quite rare in Germany, and their local headquarter opened just months ago. The car I saw was from Holland, and I was quite curious when I saw it. Very big, but they managed to nicely hide the length. And it also appears to be rather tall - great for cabin space, but design wise a few inches less would do wonders. Maybe some day they will build a Coupe version?
I still think the Mercedes S-Class looks a bit better, but the Tesla is definitely right up there with the A8 and 7 series.
