Recently, I got a CPO S85 that I am absolutely loving. At pickup, there were a few due bill items to address. My car has been dropped off today at the Service Center to take care of these this week, and I've been provided a loan P85 w/ Autopilot. I thought I would share some notes on the differences I am experiencing between these two cars in the hopes it can be useful to others. Some background... My Car: S85, no parking sensors, no Autopilot, air suspension, standard 19" w/ Goodyears, standard headliner, premium lighting, tech package w/ power liftgate, firmware 2.4-.188 Loaner Car: P85, parking sensors, Autopilot, coil suspension, 21" w/ Continental, black headliner, no premium lighting, tech package w/ power liftgate, firmware 2.4-.160 Some hardware differences (references the P85 unless specifically noted to be my S85)... - The P85 w/ Autopilot is already a unicorn, but there are a couple surprises. The chargeport is not auto-closeable. Guess this came a few weeks later from the build of the loaner - No fog lights (or at least, no option to turn on/off in controls) - Performance tan seats do indeed have alcantara inserts and this vehicle has dark gray piping Driving impression (again, P85 unless specifically noted)... - Takeoff is a good bit quicker - With my driving style, highway driving is roughly the same. NOTE: This does not mean the P85 isn't quicker, but the way I drive I do not use the performance here - With my driving style (and quite likely the roads I normally drive on), no appreciable difference in road feel between 19" Goodyears with air (my car) and 21" Continental with coil (loaner). Again, this doesn't mean there is not a difference, but my driving style is not in tune to notice the difference - I particularly like the blind spot monitoring UI. It's unobtrusive and I can notice it in my peripheral vision while I pay attention to the road. That said, it hasn't exactly been tremendously accurate - TACC is very nice, but the car has a different driving personality than I do. I would imagine I would absolutely love this in rush hour on the interstate, but I rarely drive in such traffic. As such, while it is nice to have, I am happy with the money I saved buying a CPO and foregoing it than buying a new car Other things I noticed... - The screen with the speedo is MUCH laggier with the regen/power display than my car. I am half-tempted to try rebooting the screen and seeing if that helps. - I MUCH prefer my metallic dolphin gray to the glossy black. If I had to choose between glossy black and obsidian metallic black, I would pick the metallic in a heartbeat, sight unseen. - I dislike the tan seats, as I suspected since I am generally not a fan of tan seats - I would have ordered black headliner and gray seats, but white (standard or alcantara) headliner and black seats was my fallback if I did not build to order. After just an hour of driving around, I would now pick a white headliner even if ordering new. - Not have the two side-lights in the trunk seriously darkens the trunk. Not that my trunk is well lit, but its usable. I would not be able to get by without the extra lighting of the premium lighting in the trunk. Now I am not surprised others are finding the cord bundle and adding those in or running their own LED strips to augment the built-in lighting. - The ambient lighting is a nice touch in my car. I actually miss it while driving the loaner - The yacht floor causes the "bowling alley" to lose a few inches in depth! My Diono Travel Pal sits very differently with the yacht flooring installed in the loaner than my carpeted car. I actually plan to post in the "must have accessories" thread to remove the Travel Pal from my recommendations for new cars. - The parking sensors yell "stop" when the bush next to the parking space is close to my side, even though I am pulling in parallel to the bush. - I really wish there was a way to push/pull a profile from one car to the other. My driver seat settings, mirrors, steering wheel, radio favorites, Slacker selections, etc. are missed. I went ahead and paired my phone with the loaner and am streaming Pandora instead - I miss being able to use the app to turn on the car's a/c before I leave the office - I had to find my garage door opener since the opener is at the maximum number of remotes programmed Feel free to ask questions or post other thoughts and I will try to do my best in comparing the two cars.
