I suppose premium in Europe is luxury in the USA. Isn’t a 7 series BMW about $140k USD?
I think the Mayor of Belfast still rides in the back of a 7.
But both the S-class and the 7-series are very VERY rare luxury cars. I see thousands of 5-series and E-classes for every 7-series or S-class. The difference in price must be huge in europe compared to the US, because there I saw tons of 7-series and S-class was almost as common as E-class.
