I am considering trading in my P85 for a P85D. I wanted to get real world experience/opinions from those who have made the switch. My questions are: In your experience/opinion 1) Do you feel the fit and finish of the P85D is better (or on par) as compared with the p85 you had? My current MS is good, but there were little issues (most resolved). Still have some minor ones. Hoping QC has continued to improve. 2) Is the sound proofing better? Is the car noticeable quiet as compared to the old one. I had read Tesla supposedly added more sound proofing. 3) How is the handling with the all wheel drive? Is the car "true to lane" (easier to keep straight on the interstate without many minor corrections). Not that mine isn't good,just wondering how the extra weight and motor impact, if at all the ride. How is it around cornering, etc. 4) Is the blindspot detection and other enabled like features effective/worthwhile. Overall are you pleased you went to the P85D or in hindsight, would you have waited longer to see what other improvements were made in the near future? Considering I will take a fairly substantial financial hit to make the move I'm hoping for more than what I have in regards to the fit/finish and handling (don't want to take a perceived step back). Anyway thanks for your time and input.
