I went from a 330i vert to a 335I vert. When on narrow UK rural roads the car when pushed feels like it's in a video game, probably this will be worse with an X3 with electric PS. I have to back off and control myself. On highways the effortless performance is wonderful.

A lot depends on the driving you do and the type of driver you are. I find that when driving fast the greatest enjoyment comes when I'm pushing the car close to its limit. The 335i is too fast to be driven close to it's limit frequently. The most fun car I even drove was an MGB - desperately slow nowadays with little grip but the feedback from the car and sheer reward for driving it well was fantastic. So for me sheer performance is attractive but not the whole story.
