10 most disappointing cars of 2011

The X6 is marketed as a "sports activity coupe" that combines the attributes of an SUV (high ground clearance, all wheel drive large wheels and tires) with the stance of a coupé (bold styling, dramatic sloping roof). BMW sales are hot, but buyers are apparently confused by the concept, put off by the chunky styling, or deterred by the high price -- close to $100,000 for the turbocharged M version. So far this year, BMW has sold just 1,559 of them versus more than 10,000 of the more conventional X5.
