Just saw an A45 AMG in the states...how?

I'll preface this by saying yes it was an A45, not a GLA or CLA. I could tell because it was a legitimate hatchback and had the A45 aero package (wing and such). This was in Sausalito, CA. Seeing as these are not sold in the states, I'm wondering what are the possible ways this car got here? via /r/cars http://ift.tt/2uHGhsR
