 My wife and I love our X5 but with two kids (3 and 4)we were busting at the seams.  We drove a Honda minivan first and then the R350 on a whim -- in our view, the R offers 85% of minivan functionality but feels 250% more refined.  So, we snaped one up on an manufacturer subsidized lease, (monthly pmts less than a Honda!) and immediately packed up the family for a trip to the NC mountains where we drove 40 miles up and down hills with switchbacks that would have made me sweat even in my BMW 330i.  The R inspired confidence and never lost composure even when late braking on decreasing radius turns going down a steep grade!  To me, this represents a level of active safety that few can match.
