I can no longer wait for the diesel so I have to decide on a new vehicle soon. Being an IT geek I am leery of the new UConnect system and concerned about the air suspension. So I am comparing the GC to an ML which is simpler tech wise but much more expensive. What is the latest version of UConnect and have the early bugs been fixed? Since I am keeping the car for a long time do I have reason to be concerned about either the 3.6 or hemi, the transmission or air suspension?
