I just got home from the dealership with the car, I had to drive almost 180 miles to get to the dealership but it was worth it. This car is so quiet compared to the M4 that I traded in that was always causing argues with my wife whenever I was accelerating it on freeways. With this X6 I drove with about the same speed as I drove yesterday with the M4 but my wife was so quiet. I love how comfortable this car is, I won't regret a second that I got it, the only thing to regret is that I did not get it earlier, but then I would have wanted the M4.
