 Have over 3000miles and love this SUV. The bluetec diesel is just amazing. Power/torque and smoothness combination is addicting.  Averaging 26mpg combined.  Just came back from a trip to Lake Tahoe.  SUV felt very strong and stable at high altitude and temperature in the teens.  Interior is also excellent except for the 2nd row seats.  They should slide and recline like those in R350.
