I have been planning on buying the 160 mile range S, as my daily driving very rarely goes over 80 miles (at the very most 100 miles on rare occasions) At first I had always assumed that the 160 mile pack would be perfect for this, but now I am starting to have doubts. Apparently it is bad for the battery to charge to the full 160 mile range all the time, so I am going to loose some range because of that. Also, since my drive is about 70 miles at 65-70 MPH and 10 miles at 35-40 MPH, I figure that I will loose some range to that as well. In addition, while my car will be parked in a garage at night charging, during the day at work it will be parked outside, and during the winter is can get quite cold. I can only assume that this cold soak will cost me some range as well. The final concern is battery degradation. Even if the 160 Mile Model S works for me today, will it still work for me in 75,000 miles? These concerns are not an attempt to bash Tesla or the Model S, more of an attempt to determine if I need to push back buying one a little bit until I can afford the 230 mile pack. Is there anyone who is familiar enough with this technology to give me at least a semi-accurate assessment on the viability of the 160 mile Model S for my needs? Any help with this would be greatly appreciated.
