Can not choose between used X6 and RRS. Now own X5 E53 4.8is.

X6 is faster than RRS.
X6 not behaves as SUV on the road which is good.
X6 has newer Navi and control systems

RRS looking great outside!
RRS is bigger than X6
RRS has old fashioned interior from Discovery3.

Has anybody the same concerns?

P.S. Not talking about new RRS S/C 5.0 which is best but very expensive.
