Seems that you do not understand how most Europeans think...

Person interested in new 991.2 GTS would never think about used R8 V10 or Huracan. Finding used 570S in EU is also pretty difficult task since almost all used ones are dealers demonstrators that are fully loaded with options (usually all CF) and are not cheap at all. 

Also, in EU pretty important point is socially acceptable.  And 911 is that kind of the car, even in my home land which is pretty socially sensitive.
