I've had my Model S 60 for over 3 months and 5200 miles and am still loving it.
I'm aware there will be some degradation of the battery capacity over time. My use history is that I daily charge to 80 to 90% of capacity. It's only been charged to 100% on 3 or 4 occasions. (once at delivery)
I notice that my full charge rated range has dropped from 208 miles when delivered to only 198 today.
Is this typical?
Another interesting bit is that while on a trip I left the car unplugged in the garage for a week and the daily loss of charge was about 4-5 miles of range per day.
I've also found that a good rule of thumb is that a long up-hill trip in mountains will consume 3 miles of range for each mile traveled. (900 W*Hrs/mi) This means a 110 mile trip from San Diego to Lake Arrowhead in the San Bernardino mountains, with the last 10 miles all up-hill, will consume about 140 miles of rated range with normal driving.
