It happened only on a few agencies, but this is not global, you can not go to a carshop of BMW and try to buy one of their cars with bitcoins, because they do not accept it
But you can't deny that it is a big step for for us who pushes the use of bitcoin. We should be glad that it already started and people will tell themselves that "I think I might do it too". Until every people around the world brags on how it feels amazing purchasing an expensive brand of car with bitcoin and you are the first persons who did it through history.
