I like the customization options, mainly the one for the doors to automatically lock at a certain speed or shift point. If you have kids its a must have feature.
I find the doors are slow to unlock. On my previous BMW, I grabbed the door handle, pulled and doors immediately unlocked. I find on the GV80, I have to grab the handle, wait for unlock, and then pull on the handle. On the new X5, the doors lock/unlock on proximity of the key. I wish GV80 had that feature.
