X5 vs 550ix

[TheX5]

I have a 2011 X5 50i spec'd out that is waiting to be put into the order system for a September build, but the 550ix has recently caught my attention.

In many ways these two vehicles are apples and oranges, but when I look at my "profile" I'm wondering if the 550ix may be a better choice.

As a little background, my wife and I are in our 40s, no kids. Lead a pretty active lifestyle e.g. head up to Lake Tahoe numerous times during the winter.

I do like the ride height provided by the X5, and I think I prefer how it looks over the new 5er - It just seems to be more youthful vs the 5 being more staid, but I admit this is totally a personal feeling. I definitely like the better fuel efficiency of the 5, as well I think some of interior elements such as the instrument cluster and steering wheel (looks like you can control adaptive cruise from the steering) etc are more up to date.

Obviously these are two great choices, and I don't think there is a wrong or a right here, but I am definitely feeling a little torn (though I am leaning more towards the X at this point)

As an aside, I'm not a fan of the GT.

I was wondering what other folks on the board thought about the two vehicles and if anyone else has been having the same dilemma
