I stand by what I said in the other thread: the X6 is a vehicle without an audience in the USA.
• It is obviously not a family vehicle because it has a small truck and tiny back seat; no one with kids or parcels to carry is going to want to bother with it when there are so many other (more practical) choices: the ML, the Cayenne, etc.
• it is too expensive for most single guys (would a woman even consider this SUV?) unless you happen to be the recipient of an AIG bonus. It is 10-25K more than an X5.
• the most likely buyer is a DINKs household and even there the vehicle has problems. I sat in the front and back: the vehicle is huge with a tiny, cramped interior. One can easily tote around 5 people comfortably in an ML. That’s impossible in the X6.
No sale.
As of the X6 intor, they were sold out of them, even though now you might find a couple on the lots. They were shipped and produced in limited numbers. And the X6 was meant to be a SUV coupe version of ...the 6 series, like the X5 is a SUV version of the 5 series, and X3 is, and the X1 is...so they knew it was gonna be cramped, just like the Mercedes CLS has little head room in the back due to it's swooping lines. But they still sold. I liked the X6, in black...
That's what i was kind of confused about.....
Why spend all this time/money on developing some super SUV, when as you said, what about a new CSL or Z4M?
Just seems like an odd time to release these super SUV's............but hey, people will buy them.........just look at the X6
and i'm sure there are some BMW purists out there who think that adding an M SUV cheapens/tarnishes the M badge........

As far as the M3 CSL, BMW said that there is no market for it, yet they of course say there is a market for X6M and the X5M. The Z4, well it's now a hardtop convertible, and the Z4 based m coupe didn't sell very well (i liked it), so one could in theory pick up a one on the cheap.
The same people who say putting a M badge would cheapen the brand, are the same ones who want BMW to build a M7 to competed against the S65 AMG's 9but BMW lets Alpina build the B7's)
The same type of people who cry that Porsche built the Cayenne are now applauding the move, plus Porsche is now on their way to acquiring VW, a small company owning a bigger company...That is amazing.
