My wife and I own a model S75D 2016 AP1. It's her car!! I need a car now for myself. I was waiting for the model 3 to come out but know I will need all of the storage that the model S offers to carry my work equipment. With the new pricing arrangements on the model S I maybe ordering a base no options selected, S75. My situation is this will be a work car for me 30k miles/yr, daily driving 120-150 miles everyday. So the 8yr unlimited mileage drive unit/battery coverage is important to me. The only things besides the lower cost that was pushing me to cpo are the 85 battery size and glass/pano roof, and power liftgate all for cpo average price of 57-60k. Thanks to the new pricing options including now the glass roof and the liftgate I feel I may just buy the lowest priced new tesla and yield 2-2.5 more years of drive train coverage and the 7500 tax incentive! So long story short without purchasing the AP2 options (which I can later) are any of the other of the cars capabilities possible? TACC, self parallel parking, summon?etc.... anything besides AP on the highway missing? Or are all of those capabilities part of the AP2 software option? I just can not figure this out from the tesla website? Anyone else not order the AP2 option and have any experiences you can share please. Here is a pic of all my gear in my wife's car just to make sure it all would fit. It does with the rear seats down!
