I understand what you are saying, but why would you leave your VX for that? If we are playing the question that way, would you leave your VX for a jet plane, perhaps a helicopter, maybe a Chevy Aveo or Nissan Leaf?
I interpreted that the question as the Rover as a replacement for the VX. That thing is not a replacement for the VX by any stretch of the imagination, no more that a pair of socks is a replacement for a pair of boots.
I do get what your saying about the VX, with the exception of the head turning stares, what is the purpose of you driving the VX? Not saying you shouldn't, but if mpg,reliability and luxury are your goal, I would find a swagger wagon, those things are sweet!!!!! My friend has one, gets good mpg, super quiet, very versatile, can even tow a small boat!! Its also half the price as that rover.
HAHAHAHAHAHAHA, but seriously, his van is pretty sweet as a family vehicle.
