Very interesting stat you shared doug. I had never thought the X6 would actually be smaller in terms of rear space than the X3. I always thought X3 was relatively roomier...
I also think since X6 is essentially a larger vehicle compared to the X3, the crampiness of the rear makes it look even more smaller than X3 ...
Having said all this...the X6 still turns my head and I think it is one of the sexiest vehicles in the market...I think me and my wife agreed that we enjoy watching it passby more than we would want to own it..
