That’s a statement that’s easy to make from a privileged position. Luxury is in the eyes of the beholder, and that car costs two thirds of the median income (before tax, healthcare, housing, food) in the USA.
It's the same in Western Europe, the difference is that cheap lease deals and finance have made them affordable for a significant amount of people and so these cars are extremely common. You see more 3 series than Toyota's or Hyundai's.
Every sales graph I've ever seen has relatively cheap cars such as the Fiesta, Golf, Corsa, etc. at the top. Not big Mercedes or BMWs.
