They do exist! I saw a P85D at the Nashville store today. Also got a S85 loaner for my 37500 service. I cant believe some of the changes since I got my P85 in June 13. In particular the precursors to auto pilot were a big surprise. I couldnt figure out why I got a vibration like a rumble strip every time I got close to a line and a little tug when I changed lanes without signaling OOPS. Others are nice but I still like my P85 better than the S85 and I don't really know why. Now the P85D strains my loyalty.
