I agree that the battery looks to be in excellent shape. If your commute is 20 miles each way you should be set for a long time, especially with charging at both ends. Snow on the roads and using the heater when it's below about 20F outside will both take a significant hit on range but even in those conditions I'd say this car will do 20 miles each way for a very long time. Summer and nice winter days you can probably just charge at work, especially if it's free
It does look like the car is about to drop it's first capacity bar, which usually happens around 85% SOH but that doesn't really affect anything except potential re-sale value.
