Our lease was up on our '07 X3. We looked at the GLK, LR2, and Volvo XC60. None of them drove as percisely as the X3, however as this is my wife's vehicle comfort is more important than sportiness. The GLK by far was the most refined in terms of quietness and smooth ride. While the GLK is not quite as roomy as the X3 (backseat and cargo area) it has a very relaxed manor about it - while the X3 is always taut. Both have impeccable build quality - really outstanding, with an edge going to the GLK for a satisfying door shut, although the X3 has superior inside door handles. I recommend the GLK for its refined comfort in a tidy sized package. Aggressive drivers need not apply.
Electric lift gate. Cruise Control lever. Ride and quietness. Flawless build quality and solidity. Driver information.
Inline 6! Not very impressed by the gruff 90 degree 3.5L V6. Not as quick to rev nor smooth as a BMW I-6 (what is?) 7-speed trans is very nice and smooth, but not as responsive as the units BMW uses (ZF and GM sourced). Backseat space is a disappointment.
