I chose the P85D and have been very happy with my decision. The smaller frunk made no impact on my decision, as the model S already has lots of storage available inside. I also figured that most people don't use the frunk very often because you have to be careful when closing it to not crease the hood. I've been avoiding using it for that reason.
I go to the store, put what I've purchased in the back, close the hatch and drive away. The frunk just seems like it's for longer-term storage, like if you want to always carry a blanket for an emergency picnic, and some flares. In this case, the size is not that important.
I was not too concerned about range since 99% of my normal driving is all within 100miles. It would be nice to see them improve the range back to the P85 level, and I expect Tesla to accomplish this since it is something they originally promised, and there is currently no "Eco" or "Normal" mode in the P85D.
I will tell you that you will never get tired of the acceleration and performance. I picked up my car from the factory a week ago, and I've been having lots of fun showing people how to flatten their eyeballs against the backs of their skulls.
I received the car with the regular seats, and will have them swapped out for the next gen seats in a few months. I sat in the next gen seats at the showroom and they are much nicer -- worth the wait!
