also think this way:
Macan S will have Macan Turbo above, everytime you drive pass a MacanT you won't feel happy seeing it, and probably you wish you spend some more get the top line model.
X5M, the flagship high performance SUV not only unique&stunning in BMW production line, but also stands out among most high performance SUVs (CayenneT/ML63/RRS/RRSS...you name it)
So do yourself a favor buy something you won't regret throughout your ownership
