I recently upgraded to a X5 4.8 with Sport Package from an 2005 Touareg V8 with the air suspension. The X5 is so flat and stable in corners, even at high speeds its unbelievable. The dash layout is nice, but the VW's MFI/gauge display shames the BMW. The iDrive system is nice, but lack of touch screen entry is SORELY missing and the navigation interface leaves a lot to be desired when I compare it with my wife's Buick Enclave which is simpler to use, more elegantly designed, and is so much more functional. The real time traffic data is nice. The 3rd row space is a waste, I'd rather see more legroom in the second row. The comfort seats are great and don't forget - it's fun to drive!
