We went for the 70D. While the extra acceleration of the 85D was nice, it felt as though it resulted in a narrowing of the 'normal around town' accelerator pedal position range... and it seems that Tesla doesn't give the user any accelerator remap capability (which kinda blows). Maybe we're just used to having our Leaf in Eco mode all the time (stretches the early part of the throttle map out so you have a lot of fine control and compresses the end of the map, so you just mash it to the floor if you want the car to go).
As for range, more range is always nice but we felt that the extra $10k for 30 EPA miles wasn't really worth it given our use case. Instead, that $10k can be saved and put toward a possible future battery upgrade (when the $/kWh ratio will be more favorable).
