If I were Tesla, I would absolutely exclude wagons, because it makes my numbers look worse, and IMO it's legitimate because it's a different body style (I'm a wagon lover, but I own a Model 3).

I can understand them excluding wagons if they did. The issue is I don't know what these numbers actually represent so it's hard to draw any conclusions. Is there somewhere with more detail on what numbers they actually used for the "Global premium vehicle sales" graph on page 8?

3 series wagon is no longer sold in the US, sadly.

That is sad. But this raises another question, is Tesla only quoting US sales here?
