X5 seems to be popular with soccer moms here in Alberta. So I've seen one guy driving at an X5, loaded 4.8is at my golf course. The rest are like Range Rovers drivers trophy wives and soccer moms
As far as X3 it's my 1st BMW and I picked it because it was smaller. Not a fan of huge SUVS and the X5 seemed to be a waste of space for a 90% of what I need to carry in my job and on weekends.
