The entire BMW X6 production run for 2008 has been sold. While there are still a smattering of vehicles available at some dealers, every one scheduled to depart the Greenville, SC production facility has been spoken for by a dealer, many of whom report a long waiting list for the new SAC. This doesn't surprise us at all; the X6 is one of the best driving vehicles made by BMW, easily eclipsing sports SUV competitors like the Porsche Cayenne and Range Rover Sport. In fact, in a competition with the Mercedes CLS, we'd put our money on the big bimmer every time. [via BMWBlog] Thanks to Horatiu for the tip.
