I am a model s September 2016 75d owner trying to help out a friend and coworker decide on their first Tesla. They have the option to bulid a new 75d to spec or take an inventory 90d at a deep discount. Both vehicles are in the 90k range after all options are considered. Now that the new 75s have a performance bump, the line stars to blur. The 90d has the tan leather, and my experiences have been that the newest white and black seats are infinitely more plush and comfortable to be in, which would be an advantage in a vehicle that is so fun to drive. My suggestion is to build a 75d to he and his family’s liking, as the latest iteration of the model s is super comfortable to sit in and drive. His main hang up on this idea is the range of the 90d. I was hoping to generate a good discussion of pros and cons from experience on this forum so that I may point him here to read and make a decision not only based on my experience, but of other owners all over the world, and to welcome another member to our Tesla family!
