here's my thoughts.

I have owned 3 x X5's within the last 5 years & 1 Cayenne Turbo.
The first two X5's were 3.0sports, the third (current ride 3.0diesel sport)

The CT without question was the best ride we have ever had, hands down.
However it was shockingly expensive to run & maintain & we bailed out and got into the X5 diesel.

14 months later we are missing the Cayenne a lot, enough to even put up with the running costs.

The new facelift Cayenne looks better in my eyes & with improved HP I would consider the S variant.

I have a 1K deposit on the 07 X5 due in April/May but after seeing yesterdays Cayenne press release, I am now considering going back to the Porsche group.

Air Suspension is a must though, the ride without it is god damn awful.

BTW: I feel there's too much black plastic going on with the X5 exterior.
