So, I've owned my S85D for just over a week and wanted to report my thoughts on Autopilot: it's amazing! For anyone who's thinking of buying a CPO without it, is seriously give it some more thought. I had to drive from Seattle down to Tacoma (1 hour) and back this past Friday and I used Autopilot on both legs. Engaging and disengaging it were easy. I was impressed with two aspects of its performance: Lane keeping - it did an excellent job of staying centered in turning and twistings lanes. Much better than myself. Pacing - it kept about a 3 car length buffer between me and the car in front and did a great job of tracking its speed and accelerating and decelerating properly. I can easily see how Autopilot will make longer road trips much more pleasant. I'm very glad I prioritized this feature for my CPO purchase.
